little, or a furrow plowed against it to prevent 
an occasional disposition to dig under. 
Protecting trees against rabbits. The de- 
vices that have been recommended for protect- 
ing trees from rabbits are too numerous for 
separate mention. The majority consist of 
paints, washes, or smears supposed to be dis- 
tasteful to the animals. Unfortunately, those 
that are sufficiently permanent to afford pro- 
tection for an entire winter often injure or even 
kill the trees to which they are applied. Coal 
tar, pine tar, tarred paper, and various oils are 
likely to kill young trees. Blood and animal 
fats when freshly applied will protect from 
rabbits, but are objectionable, since they are 
highly attractive to the destructive short- 
tailed field-mice. Carbolic acid and other vol- 
atile substances afford only temporary protec- 
tion, and must be renewed too often to justify 
their use. Bitter substances, like commercial 
aloes, or quassia, are useless against rabbits. 
Among the most promising washes that have 
been recommended for tree protection is the 
‘‘lime-and-sulphur’’ wash, so effective in win- 
ter for the destruction of the San Jose scale.
