(Machinery requires no repose; and therefore d, the distance
per day, is convertible into v, the velocity of movement.)
As an example:--Suppose a man is able to walk 10 miles a day, with a load
of 130 lbs., and 33 miles a day when he carries nothing. Then, from
equation (1), the value of b (the burden under which he would be brought
to a standstill) would be about 267 1/2; and the best load for him, from
equation (2), would be 119 lbs., which he would be able to carry,
according to equation (3), 11 miles a day.
Horses.--The mode of taking wild horses is by throwing the lasso, whilst
pursuing them at full speed, and dropping a noose over their necks, by
which their speed is soon checked, and they are choked down.
Mr. Rarey's sixpenny book tells all that can be told on the subject of
horse-breaking; but far more lies in the skill and horse-knowledge of the
operator, than in the mere theory. His way of mastering a vicious horse
is by taking up one fore-foot, bending the knee, slipping a loop over the
knee until it comes to the pastern-joint, and then fixing it tight. The
loop must be caused to embrace the part between the hoof and the
pastern-joint firmly, by the help of a strap of some kind, lest it should
slip. The horse is now on three legs, and he feels conquered. If he gets
very mad, wait leisurely till he becomes quiet, then caress him, and let
the leg down and allow him to rest; then repeat the process.
