INTRODUCTION. 
A Classification of Animals from the point of view 
of Economic Zoology. 
Group A. — Animals captured or slaughtered by man for food, or for 
the use by him in other ways, of their skin, bone, fat, or 
other products. 
Examples. — Animals of the chase ; food-fishes ; whales ; 
pearl-mussels. 
Group B. — Animals bred or cultivated by man for food or for the use of 
their products in industry or for their services as living 
things. 
Examples. — Flocks and herds ; horses ; dogs, poultry ; 
gold-fish ; bees ; silkworms and leeches. 
Group C. — Animals which directly promote man’s operations as a civilised 
being without being killed, captured or trained by him. 
Examples. — Scavengers such as vultures ; carrion-feeding 
insects ; earthworms and flower-fertilizing insects. 
Group D. — Animals which concern man as causing bodily injury, some- 
times death, to him, and in other cases disease, often of a 
deadly character. 
Examples . — Lions ; wolves ; snakes ; stinging and parasitic 
insects ; disease germ-carriers, as flies and mosquitoes ; 
parasitic worms ; parasitic protozoa. 
Group E. — Animals which concern man as causing bodily injury or 
disease (both possibly of a deadly character) to (A), his stock 
of domesticated animals ; or ( B ), to his vegetable plantations ; 
or (6'), to wild animals in the preservation of which he is 
interested ; or ( D ), wild plants in the preservation of which 
he is interested. 
Examples . — Similar to those of Group D, but also insects 
and worms which destroy crops, fruit and forest trees, and 
pests such as frugivorous birds, rabbits and voles.
