Nick did so, and on the last but one his parent tripped him. A few pointed questions showed the boy that he was wrong. Then the hearty "Yaw, yaw, yaw!" of the father rang out, and looking at the solemn visage of his wife, he asked:
"Vy you don't laughs now, eh? Yaw, yaw, yaw!"
The wife meekly answered that she did not see anything to cause mirth, though Nick proved that he did.
Not only that, but the son became satisfied from the quickness with which his father detected his error, and the keen reasoning he gave, that he purposely went wrong on the first problem read to him with the object of testing the youngster.
Finally, he asked him whether such was not the case. Many persons in the place of Mr. Ribsam would have been tempted to fib, because almost every one will admit any charge sooner than that of ignorance; but the Dutchman considered lying one of the meanest vices of which a man can be guilty. Like all of his countrymen, he had received a good school education at home, besides which his mind possessed a natural mathematical bent. He said he caught the answer to the question the minute it was asked him, and, although Mr. Layton may not have seen it before, Mr. Ribsam had met and conquered similar ones when he was a boy.
While he persistently refused to show Nick how to solve some of the intricate problems brought home, yet when the son, after hours of labor, was still all abroad, his father would ask him a question or two so skillfully framed that the bright boy was quick to detect their bearing on the subject over which he was puzzling his brain. The parent's query was like the lantern's flash which shows the ladder for which a man is groping.
The task of the evening being finished, Mr. Ribsam tested his boy with a number of problems that were new to him. Most of them were in the nature of puzzles, with a "catch" hidden somewhere. Nick could not give the right answer in every instance, but he did so in a majority of cases; so often, indeed, that his father did a rare thing,—he complimented his skill and ability.
