twigs removed and burned. Just as a surgeon sterilizes his instru- 

 ments so the knife used must be sterilized. If the wood is healthy 

 looking where cut, well and good; but if there is a brownish discolora- 

 tion below the bark a new 

 cut must be made lower down. 

 The discoloration shows that 

 the disease has worked lower 

 down than the cut. Remem- 

 ber: Sterilize the knife every 

 time before making the cut. 

 A tablet of corrosive sublimate 

 in a pint of water is the steriliz- 

 ing solution which may be 

 applied with a sponge or a rag. 

 It is a deadly poison and must 

 be kept where it will not be 

 reached by children or pets. 



Before spraying for any- 

 thing be sure to know whether 

 it is a bug or a disease. If 

 a bug know whether it sucks 

 or chews. Then be thorough. 

 For medium-sized gardens and 

 orchards a knapsack spray 

 pump and the portable com- 

 pressed air sprayer (Fig. 69) 

 are very satisfactory; for little 

 ones and small plants the 

 squirt-gun styles may answer. 

 Areas larger than a quarter of 

 an acre are easier to manage 

 with a barrel sprayer. In 

 choosing such an apparatus 

 give preference to one lying on 

 its side to one standing on end, 

 because when so mounted the 

 pump is lower, there is less 

 danger of its catching in 

 branches and being tipped 

 over, and the sediment settles 

 immediately below the pump 

 and is removed before it gets
