Jim's book was now becoming daily a subject of more and more excitement to him, and consequently of jealousy amongst some of the party, and particularly so with the old Doctor; as Jim was getting more rapidly educated than either of the others, and his book so far advanced as to discourage the Doctor from any essay of the kind himself. Jim that night regretted only one thing which he had neglected to do, and which it was now too late to accomplish--that was, to have measured the length of the cathedral and ascertained the number of steps required to walk around it. He had counted the number of steps to the top of the grand tower, and had intended to have measured the cathedral's length. I had procured some very beautiful engravings of it, however, one of which Daniel arranged in his book, and the length of the building and its height we easily found for him in the pocket Guide. The Doctor, watching with a jealous eye these numerous estimates going into Jim's book, to be referred to (and of course sworn to) when he got home, and probably on various occasions long before, and having learned enough of arithmetic to understand what a wonderful effect a cipher has when placed on the right of a number of figures, he smiled from day to day with a wicked intent on Jim's records, which, if they went back to his tribe in anything like a credible form, would be a direct infringement upon his peculiar department, and materially affect his standing, inasmuch as Jim laid no claims to a knowledge of _medicine_, or to anything more than good eating and drinking, before he left home. However, the Doctor at this time could only meditate and smile, as his stiff hand required some practice with the pen before he could make those little 0's so as to match with others in the book, which was often left carelessly lying about upon their table. This intent was entirely and originally wicked on the part of the old Doctor, because he had not yet, that any one knew of, made any reference to his measure of the giant woman, since he had carefully rolled up his cord and put it away amongst his other estimates, to be taken home to "astonish the natives" on their return.
