Fig. 146. — Spennophilus richardsonii. Fab. After Merriam. 



Excluding the moles, the following list of depredations have 

 been laid at the door of the principal pests listed above, by various 

 correspondents : 



Jack Rabbits: "Occasionally cut down small patches of grain; 

 gnaw bark from apple trees, causing same to die ; cut off tops of 

 young trees ; eat a few small melons ; eat corn when up three or 

 four inches high." 



Cotton-tail Rabbits: "Injure carnation plants in field; plants 

 gnawed die during early months of winter. Eat off small apple 

 trees; bark old ones; one-tenth of nursery stock injured in '98 

 and '99; five per cent of apple trees killed. Do not eat plum or 

 cherry trees. Eat bark off of evergreen and fruit trees. Cut off 

 yearling apple trees ; injure evergreens and girdle plum trees ; 

 work in winter, spring and early summer. Ruined hundreds of 

 trees of all ages last winter. No injury except in severe winters, 

 when young apple trees may be gnawed. Ate bark ofif of apple 

 trees in 1902-3. Girdle young apple trees not prptected by wood 

 veneer; when snow goes over this protection they attack lower 

 branches. Destructive to apple trees ; will eat ofif limbs two feet 

 from ground; strip bark from large trees; prefer wild crabs. Eat 

 cabbage plants in summer ; fruit trees in winter."
