In the meantime, the oil spray, the gas treatment • and 

 other remedies were considered, and the Hme-sulphur-salt spray 

 selected as the method we would attempt to subdue and hold 

 in check the enemy. A steam boiler, about new, of some four 

 to six horse power capacity, was secured and the necessary 

 piping and fixtures for cooking the contents of 12 casks at once, 

 so arranged that any one or more might receive steam indepen- 

 dently of others. Casks holding 100 to 120 gallons were used, 

 fitted with faucets near the bottom for drawing ofif the cooked 

 liquid. We could learn of no place in this section where we 

 could go for advice and instruction and so, to a certain extent, 

 had, as it were, to feel our way, both as to appliances, arrange- 

 ment of the cooking plant to do the work economically, and in 

 preparing and applying the spray. Many vexatious delays and 

 perplexing questions as to why so and so, were more or less 

 present with us during this first season's attempt to save our 

 orchards by means of this treatment. Investigation during the 

 preceding year had shown us that greater infestation existed 

 than we at first supposed could be possible, that probably the 

 whole orchard was affected, here and there a tree or more show- 

 ing the insect present ; but with something like 6,000 to 7,000 

 trees sprayed, we were compelled to stop by the bursting buds. 

 During this time we used a barrel pump mounted on a single 

 horse stone-boat, one man to pump, two men to spray. We 

 had to take men who had no idea of spraying work and teach 

 them how to do the work. 40 lbs. of lime, 30 lbs. sulphur, 15 

 lbs, salt, 60 gallons water boiled about two hours was our 

 formula for that season's spray mixture, and we aimed to put it 

 on the trees very hot. In spite of more or less faulty prepa- 

 ration, frequent heavy rainstorms and the prevalence of high 

 winds nearly every day, also the necessity of covering all the 

 ground possible, these conditions preventing thorough work 

 being done, the results were to a large degree gratifying. 



The general appearance of the trees, even if they had been 

 badly infested, was that of strong vigor, the scale apparently 

 being mostly killed. The cost per tree for the job of spraying 

 was estimated at 10 to 11 cents. 



In preparing for the year 1903 spring spraying, having found 

 our boiler of entirely too small capacity for our needs, we hired 

 a Kinney Safe engine of about six horse power capacity and
