WIDTH AND ELASTICITY OF FROG. 105 



in trotting. We were laid up part of the time, confined to our room 

 from the 24th of October, and from then to the race he was in the 

 hands of another colored boy who came from the East with us. 



He won the second Embryo with him, making the third heat in 

 2:52, when again he was turned out. On Jan. 2nd of this year tips 

 were put on, the same which he wore in the race, and from that 

 time until the 28th he wiis allowed to run in the lot or exercise by 

 leading when he was harnessed to the breaking-cart. He was driven 

 on the streets of Oakland, daily, generally long drives, and at times 

 fast, the tips having been reset on February 7th, but merely paring 

 enough so that the old nail-holes could be used, and on the 23d of 

 February was the day fixed for our friend to witness the operation, 

 and see the condition of the foot. The tips were semicircles with a 

 diameter of five inches, and this brought the posterior portion about 

 three quartei's of an inch in the rear of the point of the frog. They 

 weighed seven ounces each, and were three-eighths of an inch in 

 thickness at the end, being a trifle thicker at the toe, the width at 

 the toe seven-eighths of an inch, and at the ends five-eighths. They 

 were made of tool steel, the nail-holes countersunk on the ground 

 surface, in place of being " creased," the countei-sinking deep enough 

 to imbed the head of the nail. From so little horn having been cut 

 away when the tips were reset, there was a supei*abundance of horn, 

 and the shoulder for the end to rest against was cut deeper than was 

 required to imbed the tip. The rasp was used to lower the outside 

 of the wall, beveling it to tlie gauge-mark on the outside, and back 

 as far as the shoulder. We then called the attention of our fi-iend 

 to the heels of the feet, and width and elasticity of the frogs. There 

 had not been wear enough to reduce the wall to the level of the sole 

 and bars, and it was prominent and without a break. From the 

 shoulder for the tip to rest against to the junction of the wall and 

 bars, was a little over two inches, and it would be impassible to im- 

 prove on the general contour of the foot. This our friend admitted, 

 and when tlie knife was used to cut away the superfluous horn, back 

 of the rasping, there was only a slight discoloration, which the first 

 shaving entirely removed. The enamel having been cut with the 

 rasp, it was an easy thing to cut the other portion with the keen,
