52 AN ENTOMOLOGICAL CALENDAR. 



Burn all limbs pruned during fall and winter. 



Old melon, cucumber and squash vines should be burned, 

 and all rubbish near ground which has been in such crop should 

 be destroyed. By such treament, hibernating squash bugs, 

 cucumber beetles, and the eggs of the melon louse will be 

 destroyed. 



Burn old straw stacks where straw is not needed. Sucli 

 places offer winter resting places for several varieties of injuri- 

 ous insects. 



All fallen leaves under fruit trees, berry bushes, currants 

 and grape vines should be destroyed in the late fall. These 

 afford hibernating places for insects. 



DON'T spray with arsenic. One Minnesota man did be- 

 cause the stuff was cheap. Result, some dead turkeys, and 

 dead lambs which fed on the alfalfa under the sprayed trees. 



Paris Green and w^ater at the rate of one pound of the 

 former to 150 gallons of the latter will not injure stock which 

 might graze in an orchard immediately after it had been 

 sprayed. Of course, if a large amount of the solution should 

 be dumped on the grass in one place, and stock should crop 

 that particular spot damage might result. 



Quick lime added to Paris Green solution at the rate of 

 one pound of lime for every pound of Paris Green will prevent 

 burning by neutralizing the -acid in the Paris Green. More 

 lime might be added with perfect safety. Clear lime water 

 added to the Paris Green solution would naturally produce the 

 same result. 



RECEIPT FOR BORDEAUX MIXTURE. 



For use as a liquid spray there are several formulae for 

 this very important fungicide, but the principle of making is 

 the same in each. 



Have a stock solution of copper sulphate made by suspend- 

 ing copper sulphate (blue vitrol) in a bag just below the sur- 

 face of a tub of water, at the rate of one pound to a gallon of 

 water. Make also a stock solution of lime ; use a known quan- 

 tity of good lime, slake slowdy and add water to make a thick 

 milk of lime; allow to cool before using, and always keep the 

 lime covered with w?it^r, When ready to spr^y dilute the
