be ample and a lightly sprayed top may be as vulnerable as one that has been missed. 



Codling Iloth and Bud-Moth likewise find those vulnerable areas in the top. 

 Codling lioth is about as notorious as the "cure" at finding weak spots in the 

 protective armor. 



Growers are probably very much aware of the cost in off-grade apples due to 

 inaccessible portions of the tree. They are also aware of the increase in cost of 

 materials due to covering such portions. The difficulty has been in really knowing 

 .•;■' r>t how high some trees are end actually adopting an all out program of doing 

 Gone thing about it. The Exter.jlon Service has adopted a practical goal of 18-20 

 foot trees for a number of years. It is willing and ready to give you practical 

 help in attaining this goal by a minimum of extreme measures, Y(/hy not get together 

 on a program to get this most vital job done?

Some Points of Interest in Field Station Orchard . This note from E, F, Cuba 

 of the Field Station suggests some things wiiich nearby groivers may want to visit--- 

 and look over. "Please post the men who are interested that in ray part of the 

 orchard this year may be seen severe scab on unsprayed Hclntosh; Phygon foliage 

 chlorosis; hail injury; russet on Delicious apples from sulfur and lead arsenate; 

 injury on Baldwin apples from combined sulfur and high temperatures; and mite 

 control with Crag fxmgicide. Comparisons are made of 2 oz, Phygon formulation of 

 Stauffer Sulfur Paste; Kolofog and Thiuram combined; Crag Fungicide 3iil, Thiuram, 

 Ferbam and Ortho-cide ii06, Bie materials may be appraised by examining the trees 

 for scab control, finish of fruit, and condition of the foliage. The severe 

 drought and the temperatures this season have aggravated injviry,"

A Heavy Drinker , The follovdng quotation from "This Green Yiforld" by 

 Rutherford Piatt vfas sent in by R, ¥, liYesson of Grafton. "It takes a 

 good deal of imagination to think of water traveling up the long tapering 

 cylinder of a tall tree in an unbroken column from the deepest rootlet 

 to the topmost twig and spraying out through the perforations of the 

 leaves as from a fine nozzle. Yet every leaf of the several millions 

 of a great elm — and every blade of grass ~ is constantly performing 

 like a nozzle. The spray is so fine that it is invisible. An orchard 

 of UO mature apple trees will be equipped -with about 100,000 leaves 

 each. Those UO trees, through a highly efficient mechanism, will 

 lift 16 tons of vrater a day — four gallons per tree per hour. And as 

 trees go, apple trees are comparatively smalll"

An Echo from the Past . At a meeting of fruit growers in ^lichigaii about 75 years 

 ago, a speaker discussed at some length the disease of plum trees, commonly known as 

 Black I^not, assuming it to be of insect origin. It had been noted that a particular 

 insect was frequently found inside the "Knot", But instead of being the cause, the 

 insect had arrived later and taken up its abode within the spongy tissue. This 

 mistake on tlie part of the speaker suggests that at any given time, an authority 

 imparts only what he believes to be true. As our knowledge increases, oiir interpreta- 

 tion will necessarily change. Thirty-five years ago, it was thought that apple scab 

 was \incontrollable , Today we have control measures undreamed of at the time of 

 the First World War.
