EIGHTEENTH ANNUAL MEETING. 65 



bark pits, and enlarging- and deepening them. While it is 

 true that some persons have successfully used the oils in the 

 control of the Scale, it is likewise true that more success has 

 come from the lime-sulphur, which does not have the ele- 

 ment of occasional danger, due to lack of proper preparation. 

 We have specific examples to give to substantiate the state- 

 ments here made. I feel it but justice to the fruit growers in 

 speaking of results to call their attention to these possibilities 

 in reference to the various insecticides. 



As to apparatus, it becomes important for the fruit 

 growers to get the best. The kind to buy depends upon the 

 number and size of the trees you have to treat. A large 

 grower of fruit in the future will, no doubt, use either com- 

 pressed air or a small gasolene engine. However, for or- 

 chards of fair to large size, a lever pump with an upright lev- 

 er and a cross bar for the hands will be found to be one of 

 the most economical and satisfactory pumps, but the regular 

 barrel pump will prove the salvation of our average farm or- 

 chards. The hose should be long enough to let the operator 

 swing well around the tree. One section should be twenty- 

 five feet and the other from twenty-five to forty. On each 

 section or lead there should be an extension rod. We have 

 found that the gas pipe extension rod is satisfactory. Plain 

 three-eighth inch gas pipe is cut with threads to fit to the 

 hose and supplied with nozzle attachments for nozzles. The 

 rod can be three feet, six feet, or ten feet in length, or bet- 

 ter, jointed, so that it can be taken apart as desired. The 

 bamboo extension rod is lined with aluminum or brass, and, 

 of course, is to be recommended, although more expensive 

 than the gas pipe. It has the advantage of ofiferirfg a larger 

 surface for the hands to grip without becoming heated with 

 hot liquids or cool with cold liquids, and thus becomes more 

 agreeable to the hands of the operator, but it has the disad- 

 vantage of the lining tube turning around with the bamboo 

 casing in such a way that it can not always be used with sat- 

 isfaction. 



At the end of the rod one should use a drip tin, which is 

 a disk of tin or other metal, about three inches in diameter,
