This and many another such argument caused Mrs. Jackson to waver, and having once wavered her case was lost. Peter pursued his advantage and after a whole afternoon of reasoning succeeded in winning Nat’s mother to his point of view. The motorcycle therefore was accepted in the spirit in which it was proffered and became Nat’s most treasured possession.
What sport the two lads had going and coming from work! What wonderful Saturday afternoon rides they took through the surrounding country!
Their work at the sole leather tanneries was interesting, too. Here many new phases of leather making confronted them. First there was the tremendous weight of the great skins, which were so unwieldy that they could not easily be handled and, like cowhides, had to be cut into halves, or “sidees.” In addition to this they were usually split—sometimes before tanning, sometimes after. The grain, or the side next the hair, was the more valuable leather. After being split once the splits could be split again, if desired, just as cowhides were. Some of the hides were tanned in oak bark, some in hemlock, and some in a mixture of both called union tannage.
Oak sole leather, the foreman said, was often considered preferable for soling shoes because its close fibre rendered it waterproof, and it seldom cracked. Much of the fine English leather imported into this country was, Peter learned, oak tanned. Since oaks grew so plentifully in Great Britain the bark was much less expensive there than here.
Hemlock leather—so deep red in color—was, on the other hand, used largely for heavy, stiff soles to common shoes for men and boys, since it made up in wear what it lacked in flexibility.
Union leather, being a combination of both oak and hemlock tannage, possessed the virtues as well as the faults of each; it had not the deep red of hemlock, nor the fine fibre of oak tanned leather. Still it was a flexible material and was used, the foreman told Peter, for soling women’s shoes.
Sole leather seemed to the boys a very stiff and solid stuff after the calf and sheep skins which they had previously handled.
Perhaps they did not enjoy the Elmwood tanneries quite as much as the home works at Milburn, and perhaps they longed a little for their term of service there to be completed. Nevertheless they made friends, learned much that they were anxious to know, and had their motor rides over and back each day together.
With so many of his ambitions reaching fulfilment it began to seem to Peter as if life were a very smooth sea, and it was not until June when he and Nat were transferred to the patent leather factory that he had his first experience in navigating rough waters. This storminess came about through Tolman, a sharp-tongued foreman who did not hesitate to announce that too much favoritism had been shown Peter Strong in the past.
“I bet if he ever comes to the patent leather factory and I get the chance I will take some of the starch out of him,” Tolman had been heard to declare.
