HOESE POWER. 



Before the invention and improvement of the steam-en- 

 gine, the force of horses was very extensively used as a 

 motive power ; and although its application to machinery is 

 now much less frequent, it is still resorted to, especially in 

 places where fuel is expensive. For ordinary farm labor, it 

 will probably never be superseded. The following are some 

 of the more important facts relating to the horse and horse- 

 power : - 



The ordinary work of a horse is taken at 22,500 Ibs. raised 

 1 foot in a minute, for 8 hours a day. 



The strength of a horse is equivalent to that of 5 men. 



A draught-horse can draw 1600 Ibs. 23 miles a day on a 

 level road, weight of carriage included. 



In a horse-mill, he moves at the rate of 3 feet per second 

 on a track 25 feet diameter, and with the machine exerts the 

 power of 4J horses. 



He occupies in a stall a front of 4|- feet and a depth of 10 

 feet. 



The average weight of horses is 1000 Ibs. each. 



A horse travels 400 yards, at a walk, in 4|- minutes ; 400 

 yards, at a trot, in 2 minutes ; and 400 yards, at a galtop, 

 in 1 minute. 



A horse will carry 250 Ibs. 25 miles a day of 8 hours.
