Dow Arsenate of Lead Paste 



is the most economical and satisfactory brand of Arsenate of Lead offered on the market. Its high chemical 

 analysis, combined with exceptionally fine physical properties, makes it by far the most widely used Lead 

 in the United States. Our phenominal sales of Dow Arsenate of Lead are a result of the highest quality 

 combined with the right price. Let us quote you and send you literature or samples of the material if 

 desired. This season more than any other in the past you should place your orders early because of the 

 possible freight congestion and the fact that Lead Arsenate is scarce, consequently higher prices will pre- 

 vail. We are in better position than ever to make prompt shipment and quick deliveries. Let us serve you.

Nitrogen and Apples — Nitrogen A Stimulant 



By Professor R. W. Allen, Experiment Station, Corvallis, Oregon 



A SERIES of experiments were 

 started in February, 1914, in the 

 Hood River Valley to determine 

 the eompariitive vahie of diderent ele- 

 ments of soil fertility upon the vigor 

 of growth and productivity of fruit 

 trees that had been kept continuously 

 under clean culture since the lime of 

 planting. As the land was ])ractically 

 devoid of nitrogen and organic matter, 

 the medium in which most of the soil 

 nitrogen is to be found, a considerable 

 portion of Ihe work was devoted to 

 tests of the value of nitrogen. This 

 element was applied in various ways. 

 A type of soil known as Hood Silt, 

 which predominates upon the east side 

 of the valley, was chosen for the work. 

 The orchards had been continuouslv 



clean cultivated since ijlanting. The 

 trees were of the Spitzenberg variety 

 about 16 years of age. The plats in- 

 cluded twenty trees each and were 

 selected under the most nearly uniform 

 conditions possible. The experiment in 

 one orchard was a duplicate of the 

 work conducted in the other except 

 that a small amount of caustic soda 

 was mixed in the nitrate solution 

 applied to one and an equal ([uantity of 

 caustic ijotash to the other. 



The first season, lf)14, the applica- 

 tions were not all made at the same 

 time. As a result it was observed that 

 the earliest applications, which were 

 made March 17. exerted a marked in- 

 fluence uijon the vigor of the trees 

 throughout the season, while the later
