THIRTEENTH ANNUAL MEETING. 103 



joined it to our steam pipes, giving us some ten or twelve horse 

 power capacity, and selected a place near water convenient to 

 the orchard, using- three harrel pumps on boats, same arrange- 

 ments as year previous, except one lead of hose in place of 

 two to each outfit. An average output per day for each outfit 

 was 10 casks of 40 gallons or more, or from 12 to 1,500 gallons 

 of spray liquid per day for the three outfits. The largest day's 

 work done was about 40 casks, or 1,600 to 2,000 gallons of 

 spray. Our steam outfit could not more than keep these three 

 outfits going and do our best and cook to properly mingle the 

 material so it would put on right. It required two men con- 

 stantly at the boilers. One was kept busy most of the time 

 stirring the slaking lime and drawing the liquid from the cook- 

 ing tanks and straining ready for the pump barrels. The other 

 man took care of the boilers, attended to the weighing out and 

 putting together of the materials, water, etc., and taking gen- 

 eral oversight of the plant. When working near by, the spray- 

 ing outfits came directly to the boiler for their spray, but for 

 points of the orchard more distant, the spray liquid was strained 

 directly into common casks holding 40 to 50 gallons and drawn 

 by w-agons directly to the place needed, unloaded on to a mov- 

 able platform of convenient height, the empties returning to 

 boiler for use again. This plan kept a constant supply of hot 

 liquid spray ready for the convenient use of the outfits. 



This season the formula mostly used was 30 lbs. lime, 20 

 lbs. flowers of sulphur, 15 lbs. of salt, 60 gallons water, cook- 

 ing i^ to 2 hours. Various other formulas were tried, also 

 the length of time of cooking was varied, but we seemed to get 

 the best results in putting on in above just described method. 

 About all the trees were gone over the second time when wind 

 was in opposite direction, if possible, to touch every place not 

 reached by the first "spraying. It is estimated that we used a 

 total of over 36,000 gallons of spray liquid, which required more 

 than 13,000 lbs. sulphur, 16,000 lbs. lime, and 7,500 lbs. salt, 

 costing about $500.00 ; cost of labor including horses, $562.00 ; 

 cost of coal besides wood used, $20.00 ; cost of sundry expenses, 

 repairs, etc., $25.00 ; charge for deterioration in value of the 

 plant, $50.00; a total of about $1,157.00, as the cost for spray- 

 ing about 11,000 trees, or about 10 cents per tree.
