Let the horse be the type for general discussion, 
as children are interested in this animal more than 
in any other. Under this head may come the differ¬ 
ent kinds of horses on basis of use, viz.: Draft 
horse, coach horse, race horse, driving horse, sad¬ 
dle horse; on basis of stock, Norman, Clydesdale, 
heavy draft, Indian pony, Canadian or Montana 
pony; Texas pony, etc., with the general charac¬ 
teristics of each. In connection with the study of 
the horse, read - portions of Black Beauty, by 
Sewell. 
This book gives an exhaustive treatise on treat¬ 
ment. Cows, dogs and other domestic animals 
may be introduced at many points in the discussion 
of the horse by way of comparison and contrast. 
Kind treatment should be the emphatic topic in 
every case. 
The comparative commercial value of cows, fat 
stock, horses, and so forth, may be discussed, to¬ 
gether with cost and care to be deducted in each 
case.
