A good I oviiit is e.-,sentird. The best outfit.! even .illiuviij ;■ for interest and detoriora- i tion, is cheapest in the end. The great-; est returns follow the best distribution ' oi spray, an-l tiiis is determined by the; following 1 factors: A doubling of the; pressuie doubles the quantity of spray eje-'ted. ciutincc in two the lime re■|uired for the ajjplkation. At kpressure the spray has a greater sweep. There is less Deed of individual attention to flower clusters and Ivranehes. At the lower pressure the spray loses its etfrrtiveness a few i'eot from the no/./'e,*: iii.-.'i it becomes necessary to follow along ; •almost cvei\ branch. This consumes i extra time. The high pressure .is not j wasteful of licu-iid. as manv contend : it is the. low- pressure that is wasteful of time. Lime sulphur should he appiV i with so as to penetrate every ' crack. An angle coupling is a neces- ; sit;,. Follow the branches from their' tips down to the trunk. Do not slight the ends of the branches nor overspray! tiie trunk. Above all things, be thor- j ough.
