19° 26 m. in twelve days. Their rate of travelling is, 
of course, about one hundred miles a day. What, 
in equestrian phrase, is called a great mover, will, 
without pressing, trot 640 yards in 80 seconds, and 
if pressed will go. over the same distance in 50 se- 
conds. In the first case, the rate of moving is 5 feet 
3 inches per second, and in the other, 8 feet 5 inches. 
The Roman horses, probably descendants from 
Barbs, run at the rate of 27 feet the second of time, 
and the British horse Childers, is said to have run at 
the rate of 45 feet 5 inches, and Sterling, another 
British horse, at the rate of 82} per second.(1) This 
may be regarded as the maximum of horse speed. 
The ordinary load, in France, of a four wheeled 
waggon, drawn by six horses on a pavement, is 10,000 
pounds. That of a cart, drawn by four horses, 5,500. 
With these loads, they travel 10 leagues a day for 
six weeks together. A single horse has been known 
to draw 500 pounds at the rate of 140 yards in 112 
seconds, and on the pavements of London, a single 
horse has drawn 6000 pounds for a short distance, and 
3000 for a considerable distance and with facility. 
This appears to be the maximum of horse power in 
drawing. 
Under the pack ‘or saddle, 300 pounds is the ordi- 
nary load for a horse, but according to M. Thiroux, 
a dragoon horse carries 340 pounds. This includes

lusian) well worth the attention of the rich amateurs of the United States. The names 
by which these races are known, are the Parameros and the Aqualillas. See Ulloa’s 
voyage, tome 1. page 370. In Chili also, is a race, which, for beauty, action and har- 
diness, may be compared with the horse of Arabia, and with this advantage, that they 
are very cheap, while those of Arabia, are very dear, See Molina’s Nat. Hist. of Chi- 
li, pages 505 et seq.
