of arsenate of lead, at the rate of about two pounds to fifty gallons of water. 
The lead may also be combined with bordeaux or other mixtures if desired. 
This spray should be applied at least once after the blooming time, and again 
ten days or two weeks later to kill the second brood of insects. 
Peaches and plums seem to be more susceptible to attacks of San Jos5 scale 
than apples and pears. Spray in late winter, using the lime-sulphur solution. 
Put a gallon of chemical into ev'er>- eight gallons of water. In addition to being 
effective against San Jose scale, this treatment also keeps off much fungous 
growth in addition to killing the in.sccts. 
Just after the blossom petals fall, you should spray with a weaker lime- 
sulphur solution, using the "self-boiled" mixture. To get best results, peach 
trees should be sprayed everj* two weeks until a month before the fruit ripens. 
This keeps all fungous growth in check and also prevents the other fruit-tree 
pests from getting a foothold. Curculio. that pest of the peach- and plum- 
grower, can be kept away by spraying with arsenate of lead. Just after the 
blossoms fall use arsenate with "self-boiled" lime sulphur, and repeat the 
"dose" ten days later. 
Pear trees as a rule do not require as much spraying as apples or peach 
trees. Two sprayings are usually sufficient. The first application should be 
when the trees are dormant. Fall, winter, or early spring is the liest time, but 
it is not advisable to do it when the temperatuie is Iwlow the freezing point. 
The mixture to be used is one gallon of lime-sulphur to eight gallons of water. 
The second spraying of pear trees should be done just after the blos-soms fall. 
Use lime-sulphur, one and one-half gallon-s to every fifty gallons of water, 
adding two pounds of arsenate of lead. For more detailed spraying information, 
write your State Entomologist at the state capital, or your State Agricultural 
College. The United States Department of Agriculture issue bulletins on 
spraying. Write to Washington for list of bulletins.
