Perhaps they encouraged and stimulated him to exertion, for, during the next two weeks, all his spare hours, late at night and early in the morning, were incessantly devoted to acquiring the mysteries of book-keeping and some other forms of mercantile account. To these, he applied himself with such steadiness and perseverance that, although he brought no greater amount of previous knowledge to the subject than certain dim recollections of two or three very long sums entered into a ciphering-book at school, and relieved for parental inspection by the effigy of a fat swan tastefully flourished by the writing-master's own hand, he found himself, at the end of a fortnight, in a condition to report his proficiency to Mr Linkinwater, and to claim his promise that he, Nicholas Nickleby, should now be allowed to assist him in his graver labours.

It was a sight to behold Tim Linkinwater slowly bring out a massive ledger and day-book, and, after turning them over and over, and affectionately dusting their backs and sides, open the leaves here and there, and cast his eyes, half mournfully, half proudly, upon the fair and unblotted entries.

'Four-and-forty year, next May!' said Tim. 'Many new ledgers since then. Four-and-forty year!'

Tim closed the book again.

'Come, come,' said Nicholas, 'I am all impatience to begin.'

Tim Linkinwater shook his head with an air of mild reproof. Mr Nickleby was not sufficiently impressed with the deep and awful nature of his undertaking. Suppose there should be any mistake--any scratching out!

Young men are adventurous. It is extraordinary what they will rush upon, sometimes. Without even taking the precaution of sitting himself down upon his stool, but standing leisurely at the desk, and with a smile upon his face--actually a smile--there was no mistake about it; Mr Linkinwater often mentioned it afterwards--Nicholas dipped his pen into the inkstand before him, and plunged into the books of Cheeryble Brothers!

Tim Linkinwater turned pale, and tilting up his stool on the two legs nearest Nicholas, looked over his shoulder in breathless anxiety. Brother Charles and brother Ned entered the counting-house together; but Tim Linkinwater, without looking round, impatiently waved his hand as a caution that profound silence must be observed, and followed the nib of the inexperienced pen with strained and eager eyes.

The brothers looked on with smiling faces, but Tim Linkinwater smiled not, nor moved for some minutes. At length, he drew a long slow breath, and still maintaining his position on the tilted stool, glanced at brother Charles, secretly pointed with the feather of his pen towards Nicholas, and nodded his head in a grave and resolute manner, plainly signifying 'He'll do.'

Brother Charles nodded again, and exchanged a laughing look with brother Ned; but, just then, Nicholas stopped to refer to some other page, and Tim Linkinwater, unable to contain his satisfaction any longer, descended from his stool, and caught him rapturously by the hand.

'He has done it!' said Tim, looking round at his employers and shaking his head triumphantly. 'His capital B's and D's are exactly like mine; he dots all his small i's and crosses every t as he writes it. There an't such a young man as this in all London,' said Tim, clapping Nicholas on the back; 'not one. Don't tell me! The city can't produce his equal. I challenge the city to do it!'

With this casting down of his gauntlet, Tim Linkinwater struck the desk such a blow with his clenched fist, that the old blackbird tumbled off his perch with the start it gave him, and actually uttered a feeble croak, in the extremity of his astonishment.

'Well said, Tim--well said, Tim Linkinwater!' cried brother Charles, scarcely less pleased than Tim himself, and clapping his hands gently as he spoke. 'I knew our young friend would take great pains, and I was quite certain he would succeed, in no time. Didn't I say so, brother Ned?'

'You did, my dear brother; certainly, my dear brother, you said so, and you were quite right,' replied Ned.
