4. Answer in a paragraph of about 150 words each.

Question (a)
Trace the bond of friendship between Baldwin and Gresham. Explain why Baldwin wished to attribute some credit to his friend.
Answer:
Baldwin and Gresham were boyhood chums. They went to school together. Their friendship flowered into a lifetime bondage as it was sustained for thirty five years. When Baldwin’s son was being baptised in the church, Gresham was present. Baldwin expressed his wish that his son John Gresham Baldwin grew up to Gresham’s standard in life. Baldwin was paid only 60 dollars a week for working as a Governor of the private bank founded by Gresham. Accidentally, Baldwin found out how Gresham was siphoning money very cleverly from the deposits technically without really causing any loss to the depositors. But Baldwin was loyal to Gresham only as long as he was honest. Once he parted ways with honesty, Baldwin would also part ways with Gresham. By the force of his upright character, Baldwin advised him to close the bank and return the deposit to the customers.

Third National Bank was ready to help the reorganization of the bank. Meanwhile, Gresham was arrested. The court could not nail Gresham as there was not a shred of evidence to prove his guilt. If Baldwin testified, the court would indict him. Just before being arrested Gresham offered him one hundred thousand dollars to just say “I don’t remember”. The three words to let him off the hook. He claimed it was the difference between the salary he had been paid and what he ought to have received. Had it been someone else, Baldwin would have slapped him. But it was Gresham who understood his body language and did not press the matter further. He was proud of the fact that Gresham understood how he could not compromise with his conscience. His family members Martha, Evie and John felt that it was a compliment that cost him one hundred thousand dollars. Baldwin said that Gresham’s compliment about his uprightness was worth a hundred thousand dollars.

Question (b)
How did Martha and John react when they came to know that Baldwin had rejected the generous offer made by Gresham?
Answer:
Martha and John cherished a grudge against Gresham for having underpaid Baldwin for about two decades. They openly said that he deserved punishment. Initially Gresham condemned the bribe claimed as a difference in salary paid. Had he been made a similar offer he claimed he would have asked him to go to the devil. Baldwin said that having been a friend he couldn’t use such an abusive language. Casually John asked how much he offered. Baldwin said that it was one hundred thousand dollars. Suddenly Martha and John changed their attitude towards Gresham. John viewed a shame if Gresham got indicted because he shared his name. Martha also desperately tried to convince him not to testify against Gresham. John even suggested that he could say those three words “I don’t remember” as the depositor would not lose a cent. Baldwin felt miserable because the family members who he wanted to feel proud of his uprightness wanted him to crossover to the side of corrupt practices because of the generous offer made by Gresham.

SamacheerKalvi.Guru

Question (c)
Is Baldwin really honest or does he maintain his honesty fearing criticism? Why do you say so?
Answer:
Baldwin lived the life of an upright and honest man. Though he was paid just 60 dollars a week in the private bank of Gresham, he never complained. The small increments he had been given were not because he had asked but because Gresham had given them. He was frugal and he was worshipped as a hero by his family members (i.e.) wife Martha, son John Gresham Baldwin and daughter Evie.

Baldwin deeply believed that he had been a role model to his children that is more valuable than money. He admitted to his son that he was disturbed that he would lose the respect of his own family members if he stooped even once in his life even if the bait is one hundred thousand dollars. No doubt he was upright. The three words “I don’t remember” would choke him. Only during the momentary explosion of frustration, it appears that he feared criticism. But his natural reflex on the offer was denial. His agony on the contradictory expectation of worldly-wise family members is obvious. He did not even have to articulate his feelings to Gresham who intuitively understood that his uprightness can’t be purchased with even one hundred thousand dollars.

Question (d)
Sketch the character of:
(i) Robert Baldwin
(ii) John Gresham.
Answer:
(i) Robert Baldwin:
Robert Baldwin is the central character around whom the whole one-act play revolves. He is a middle class father who values honesty and loyalty to the organization more than 35 year long friendship. He rises in the esteem of the readers and theatre goers on realising that he wants to leave a legacy of honesty to his children and not the ill-gotten hundred thousand dollars which could give his family a life of comfort they did want to lead. Baldwin is really hurt by the three sided attack (i.e.) a war of words waged against his honesty by Martha, Evie and John. Even before the trial begins against Gresham, Baldwin is made to feel like a traitor.

His family members accuse him of letting down the honour of a close family friend who had made a very generous offer. The mental agony experienced by Baldwin is hundred times more at home. He is elated initially as he had successfully forced Gresham with a whip in hand (i.e.) honesty to ‘ close the bank and make up the loss to the customers. But when he discloses the offer of one hundred thousand dollars, as a private fortune without causing loss of a cent to depositors, he is made to experience hell by the emotional blackmail of his family members who knew very well how those three words “I don’t remember” would choke him. Baldwin holds on to honesty even at the prospect of losing both 35 year-old friendship and one hundred thousand dollars he had never had in his life.

(ii) John Gresham:
John Gresham is a worldly-wise founder of a private bank. He values friendship and appoints his boyhood chum Robert Baldwin as the Governor in his bank. He is clever and is very , successful in running his bank profitably. In the meantime, he uses the deposits accrued in a 1 way that enhances his own private fortune of course without costing anything to the depositors, It is in fact a breach of trust. Nobody has had an inkling that any malpractice is going on. Even Donovan the cashier claims that the closure of the bank came as a rude shock to him as he had married on the strength of the job and salary from the bank.

Martha claims she withdrew her money without telling Baldwin who is very loyal to Gresham. He would never have approved of it. After being found out and when the trial against him on misappropriation of funds is in “progress he offers a bait of one hundred thousand dollars from his private fortune. He knows’ that only Baldwin alone could help the law to nail him. But if he says, “I don’t remember” again using the good will regained in the law suit. But he understands the body language of , Baldwin. He realizes it would be a painful thing for Baldwin to testify against him. He might be bad as a banker, but he values the feelings of Baldwin and his honesty. He confesses to avid embarrassment to Baldwin and informs ‘Third National’ chairman that Baldwin has not for technical questions, he would be let off the hook. If acquitted, he could make money budged even after the offer of one hundred thousand dollars.

SamacheerKalvi.Guru

Question (e)
Who do you think exhibits true friendship-Baldwin or Gresham? Justify your answer.
Answer:
This is a typical question for which much can be said on both the sides. Both Baldwin and Gresham exhibit true friendship from their respective sides. Baldwin is rich in great virtues like loyalty, honesty, frugality and valuing human relationships. He is loyal to Gresham with thirty five year old friendship. But the moment Gresham parts ways with honesty, Baldwin would part ways with him. The greatest compliment ever paid to Baldwin is not from Martha, Evie or John but Gresham. Gresham meets Marshall and confesses that Baldwin is an honest man whose honesty cannot be purchased even with one hundred thousand dollars.

He is poor earning just 60 dollars a week, now even that is gone as the bank is closed. He is richer than Gresham in terms of uprightness and honesty. Baldwin, being a friend, shows Gresham the right path even when he realizes that his friendship would be at stake. Thiruvalluvar says, “Friendship is not meant for just laughing and having fun but to criticize a friend when he is wrong.” Likewise, it is Baldwin who compels Gresham to close the bank and ensure the of deposits through honest means. He doesn’t want to support friendship when a friend parts ways with honesty. He doesn’t openly articulate his unwillingness to accept the bait but his uncomfortable silence says it all. Thus both exhibit true friendship towards one another.

Additional Questions

Question (a)
Explain the significance of the words ‘I don’t remember’.
Answer:
‘I don’t remember’ were the three words which Gresham wanted Baldwin to say when technical questions on misappropriation of funds are asked in the court. Gresham offered one hundred thousand dollars in hot cash to say them. But Baldwin did not want to do that dishonest and dishonourable thing. But having been honest earning just 60 dollars a week Baldwin felt like choking. His children and wife persuaded him. Gresham understood Baldwin would not say those words though Baldwin didn’t say it openly. John told Baldwin it was a compliment that cost him a hundred thousand dollars. But Baldwin felt it was a compliment worth hundred thousand dollars.

Speaking Activity

(a) Imagine you are Baldwin and your partner is Gresham. Try your best to persuade your partner to confess the truth. Build a conversation describing how both of you would react in such a situation. Work in pairs.

Gresham: Baldwin, why do you look cross?
Baldwin: Ask your conscience.
Gresham: Well, my conscience is clear. What is wrong with you?
Baldwin: I found out that you are siphoning small negligible changes to your own account. Now it amounts to a few hundred thousand dollars as none of the depositors have noticed the disappearance of small changes.
Gresham: Well, none of the depositors would lose a cent. I have transferred it in some investment. I have got ten fold gains. Now we shall quietly transfer the amount in their own accounts. No one will ever come to know of it.
Baldwin: Is it not a breach of trust? I’m not going to keep quiet about this.
Gresham: What do you want to do?
Baldwin: Close the bank and make good the loss to all the depositors. (After a few days)
Gresham: Well, Baldwin I have closed the bank. Third National is going to do the reorganisation. Now I want you to say three words.
Baldwin: What?
Gresham: “I don’t remember” When you are cross examined on vital statistics for which you would require references.
Baldwin: How does that absolve you of your crime.
Gresham: Don’t you know the fact that I’ve earned enough money and no depositor will lose a cent. It is just a technicality.
Baldwin: What do you mean?
Gresham: Well, I will give you one hundred thousand dollars for letting me off the hook. I just want you to say “I don’t remember”.
Baldwin: Already you have used the funds of depositors. You want them to become paupers?
Gresham: Baldwin, you frustrate me. Look here. This is hot cash from my own private fortune. Baldwin, why don’t you say something?
Baldwin: You have known me for more than 35 years.
Gresham: You are silent. Say yes or no. I know you have been an upright man all through your life. The offer is final.
Baldwin: You have one option Gresham. We will meet in the court. You can confess. For God’s sake don’t force me to say anything now. I am disturbed.
Gresham: Why do you think it is a bribe or a bait. It is the difference in your salary, the salary you have received and what you should have got all these years.
Baldwin: As long as you are honest, I will be loyal to you Gresham. When you part with loyalty, we would part ways. The matter is closed.

(b) ‘A friend in need is a friend indeed’. Does this hold good in all situations? Share your views with your class.

The saying, “A friend in need is a friend indeed” is relevant to only those situations when both the friends pursue the goals with justifiable means. I read an interesting story written by O. Henry entitle “After twenty years”. Two boyhood chums, Bob and Jimmy, decide to pursue their dream careers and decide to meet at Big Joe Brady’s Restaurant. Jimmy becomes a policeman and Bob a criminal and notorious robber. Jimmy recognizes the features of the most wanted criminal by Chicago police in Bob. The friend’s need is to help him escape but duty consciousness gives him painful choice of sending a plain clothes man to arrest him. So, the saying “A friend in need is a friend indeed” is not applicable at all occasions. When there is a debate with the conscience on moral grounds and professional ethics, one can’t continue to be a friend “in need”.

But Baldwin coerced Mr. Gresham to close the bank and | settle the account of the depositors. Mr. Gresham promised to return the depositors money. He offered Baldwin one hundred thousand dollars if he chose to tell the enquiry officers that he had forgotten some important details. This would help Gresham get out of the problem safely. Baldwin was shocked by the offer.

He went home and told Martha, his wife and Gresham Baldwin about the offer. On hearing the handsome offer, both the wife and son persuade him to take the money as it was just a technicality and the depositors would not lose money. Actually, Baldwin had a faith that his family regarded his integrity far higher than material gains. When he learnt his son and family members were trying to convince him to take the money, he felt disgusted. Just then, Mr. Marshal, President of third National Bank, informed Baldwin that his boss Mr. Gresham has confessed to his crime. He had told him that one hundred thousand dollars couldn’t shake Baldwin’s integrity. Though he had told him that it was a difference of salary he had paid and what he ought to have paid. He said Gresham did not want him to undergo the pain of testifying against him in the court. Hearing this, Baldwin cried. His heart felt light. Mr. marshal offered him a position in his bank. This has been the honour conferred on his honesty.

“உண்மை , தெரிந்த நேரம்” என்னும் கதையில் பால்ட்வின் நேர்மையான நடத்தையையும் அதன் பின்னணியில் முழுக்கதையும் சுழல்கிறது. இந்த ஓரங்க நாடகம் ஆசிரியர் இடம், காலம், செயல் இவற்றுக்கிடையே உள்ள பாரம்பரிய ஒற்றுமையைத் துல்லியமாகக் காட்டுகிறது. நாடகத்தில் உச்சக் கட்டத்தில் ஓ.ஹென்றிக்கே உரிய திருப்பத்தால் நாடகம் வியப்பூட்டும் வண்ணம் முடிகிறது. பால்ட்வின் வாரம் 60 டாலர் மட்டுமே சம்பாதிக்கிற நடுத்தர வகுப்பைச் சார்ந்தவர். அவர் திரு.கிரெசாம் நடத்துகிற தனியார் வங்கியில் பணி புரிந்தார். அவர்கள் 30 வருடங்களாக நண்பர்கள். பால்ட்வின் தன் மகனுக்கு கிரெசாம் பால்ட்வின் எனப் பெயர் சூட்டினார். அவர் மனம்

நிறைந்த வாழ்க்கை வாழ்ந்து வந்தார். அவர் தன் முதலாளி மிகத் தந்திரமாகப் பணத்தைக் கையாளுகிறார் என்பதைக் கண்டுபிடித்தார். நுட்பமாகப் பார்த்தால் பணம் செலுத்துபவருக்கு ஒரு பைசா நஷ்டமும் ஏற்படாது. ஆனால், பால்ட்வின் வங்கியை மூடிவிட்டு பணத்தைச் செலுத்திய வாடிக்கையாளர்களுக்கு திரும்பிக் கொடுத்து விடுமாறு கிரெசாமை நிர்பந்தப்படுத்தினார். கிரெசாம் வாடிக்கையாளரின் பணத்தை திருப்பிக் கொடுத்து விடுவதாக வாக்குறுதி அளித்தார். பால்ட்வின் விசாரணை அலுவலர்களிடம் தான் சில முக்கிய தகவல்களை மறந்து விட்டதாகக் கூறும்படியும், அதற்கான சன்மானமாக ஒரு லட்சம் டாலர் தருவதாகவும் கிரெசாம் கூறினார். இது கிரெசாம் பிரச்சனையிலிருந்து தப்பிக்க உதவும். பால்ட்வின் இத்தகைய லஞ்ச அறிவிப்பைக் கேட்டு அதிர்ந்து போனார்.

வீட்டுக்குச் சென்று தன் மனைவி மார்த்தாவிடமும், மகன் கிரெசாம் பால்ட்வினிடமும் ஒப்பந்தத்தைக் குறித்துச் சொன்னார். இதைக் கேட்ட இருவரும் ஒப்பந்தப் பணத்தைப் பெற்றுக் கொள்ளுமாறு தூண்டினர். மேலும், இதனால் நுட்பமாகப் பார்த்தால் வாடிக்கையாளர் எதையும் இழக்கப் போவதில்லை என்றனர். உண்மையாகப் பார்த்தால் தன் குடும்பத்தினர் தன் நாணயத்தின் மீது, பணத்தைவிட அதிக மதிப்பு வைத்திருந்தனர் என்பதில் நம்பிக்கை கொண்டிருந்தார். அவர்கள் பணத்தைப் பெற்றுக் கொள்ளுமாறு தன்னை சம்மதிக்க வைப்பதை எண்ணி வெறுப்படைந்தார். அப்போது தான் மூன்றாவது தேசிய வங்கியின் தலைவரான மார்சல் அவர்கள், கிரெசாம் தன் தவற்றை ஒப்புக்கொண்டதாக பால்ட்வினுக்குத் தெரிவித்தார். அவர் கிரெசாம் கொடுப்பதாகச் சொன்ன 1 லட்சம் டாலர் பால்ட்வினின் நேர்மையைத் தகர்க்கவில்லை எனத் தெரிவித்தார். அதை அவரின் சம்பளத்தில் தான் தந்திருக்க வேண்டிய தொகையின் வித்தியாசமே எனக் கிரெசாம் கூறியும் அதை மறுத்து விட்டார். பால்ட்வின் நீதிமன்றத்தில் தனக்கு எதிராக சாட்சி அளிப்பதில் | தனக்கு விருப்பமில்லை என்பதைக் கிரெசாம் தெரிவித்ததாக மார்சல் கூறினார். இதைக் கேட்ட பால்ட்வின் கண் கலங்கலானார். அவர் மன உலைச்சல் | தளர்ந்தது. மார்சல் தன் வங்கியிலேயே பால்ட்வினுக்கு | வேலை வாய்ப்பு ஏற்படுத்தினார். இதுதான், அவர் நாணயத்திற்கு கிடைத்த சன்மானம்.

முடிவுரை:
‘நாகரீக சமுதாயத்தின் குறைகளை ஆசிரியர் பிரதிபலித்துக் காட்டுகிறார். மனிதன் நேர்மை, நாணயத்தைக் காட்டிலும் பணத்தையே மதிக்கிறான். கதையின் முடிவில் கதாபாத்திரத்திற்கு கிடைக்கும் சன்மானம், ‘நாணயம் சன்மானத்திற்கு உரியது) என்பதை மீண்டும் உறுதிபடுத்துகிறது.
