8 DOMESTICATED ANIMALS AND PLANTS 
distinctive work, without which man would have failed to develop 
his civilization at certain significant points. 
Animals a means of recreation. Wholly aside from the sport 
of hunting, our animal population contributes not a little to the 
diversion and the recreation of man. The old-time tournament? 
and the later fox chase ministered to the pleasure sense of man, 
as does the modern horse race. There is no enjoyment more 
exhilarating than driving behind a spirited horse, unless it be 
that primitive pleasure of riding ; and the training of intelligent 
horses to the higher class of service is a business that rises 
to the rank of a fine art. 
Thousands of ponies contribute not only to the health of 
children but also to their pleasure and development, both physi- 
cal and mental, for no experience is better suited to stimulate 
resourcefulness in the child than is the everyday management 
of an animal of the horse kind. 
The business of fancy breeding is a refining kind of enjoy- 
ment that for sheer fascination has no superior. As the 
clay in the hands of the potter, so is a flexible species in the 
hand of the breeder, as is evidenced by a glance at what 
has been done in the breeding of pigeons and of dogs (see 
pp- 93-95), and as will become evident as we proceed with the 
study now in hand. 
Animals and plants as sources of raw material for manufac- 
turing purposes. Animals may be thought to afford but little 
raw material for the manufacturer, but the wool and the skins, 
the bones and the slaughterhouse refuse, all work up into 
valuable material for factory consumption, providing endless 
necessities and even luxuries, from the covering of our hands 
and feet to brushes and combs, buttons and knife handles, 
gelatin and glue. 
Plants and plant products are nearly all submitted to some 
process of manufacture before assuming forms suitable for the 
uses of man, and this affords opportunity for the exercise of
