As an Eastern entomologist has 

 slated, "the dusting method would have 

 died a'bornin' " had the spray gun and 

 high-powered sprayer appeared earlier. 

 I believe that his judgment is sound in 

 this respect. We have not had time to 

 test out the gun under all conditions, 

 but preliminary work seems to indicate 

 that it will in a large degree fill the 

 hill. This is particularly true of the 

 new ten - horsepower, four - cylinder 

 sprayer that is becoming popular in the 

 Hood River Valley. This machine is 

 capable of maintaining three guns at 

 a minimum pressure of 250 pounds. 

 Several growers operate their machines 

 in this manner, one man riding on top. 

 The machine passes up and down each 

 row, making necessary only a moment's 

 stop for each two trees. The spray- 

 ing of a large acreage per day is readily 

 accomplished. Figures for the 1918 

 work, not all available at the present 

 time, however, from data in hand two 



men on this high-power sprayer can cut 

 their time in two and do the work 

 much more easily than they could with 

 the 12-foot rods and small outfit. 



In some cases the old three and three 

 and one-half horsepower outfits were 

 found capable of handling two guns. 

 A little more than a third of the time 

 was saved as compared to the time used 

 with rods. This was also accomplished 

 with much less effort on the part of the 

 rodmen. In other words, the appear- 

 ance of the spray gun has in a large 

 measure taken the sting out of spray- 

 ing, making easy work of what used to 

 be decided drudgery. The handling of 

 the gun on the part of many orchard- 

 ists, however, has not been perfected. 

 Some growers are inclined to take too 

 much for granted with a result a good 

 many tree tops were supposed to be 

 covered when in reality they were not. 

 This seems to be more particularly true 

 where the gun has been adapted to the 



sprayer of low power. Some growers 

 with good outfits were inclined to estab- 

 lish speed records with a result their 

 crop suffered. Care must be taken with 

 the gun just the same as is done with 

 the rod. 



Some comparative figures are avail- 

 able with reference to codling-moth 

 control during the past season. In 

 three different orchards rods versus 

 guns were tested. In all three of these 

 orchards slightly better control was 

 obtained with the rods than with the 

 guns. These percentages ran as fol- 

 lows: Gun, 4.95 per cent; rod, 2.38 per 

 cent; gun, 7.46 per cent; rod, 4.34 per 

 cent; gun, 9.98 per cent; rod, 6.64 per 

 cent. In one of these orchards, the last 

 cited, the power outfit is a small one. 

 The fruit at harvest time was analyzed 

 as it came from the trees, that is, the 

 fruit from the ground to twelve feet 

 was separated from those higher. The 

 difference in condition was very 

 marked. The lower fruits were practi- 

 cally free from worms, though some 

 stings were present, while the upper 

 fruits were in very bad shape, a big 

 percentage of which were wormy. This 

 condition was observed in a good many 

 orchards, more noticeably where small

THE SELF-OILING WINDMILL 



has become so popular in its first four years that 

 thousands have been called for to replace, on their 

 old towers, other makes of mills, and to replace, at 

 small cost, the gearing of the earlier 

 Aermotors, making them self-oil- 

 ing. Its enclosed motor 

 keeps in the oil and 

 keeps out dust and 

 rain. The Splash Oil- 

 ing System constantly 

 floods everybearingvrith oil, pre- 

 venting wear and enabling the 

 mill to pump in the lightest breeze. 

 The oil supply is renewed once a year. 

 Double Gears are used, each carrying half the load.
