LATIMER'S DRY 



POWDERED ARSENATE OF LEAD 



For eight years Ave have been specialists in the 

 manufacture of Arsenate of Lead, but we were sur- 

 prised when during 1916 over 80% of the orders we 

 received Avere for Latimer's Dry and less than 20% 

 called for Latimer's Paste. 



PoAvdered arsenate of lead marks the greatest ad- 

 vance that has been made in spraying materials in the 

 last ten years, and this has been quickly recognized by 

 the groAA^ers. 



If you use LATIMER'S DRY once you become an 

 enthusiastic adA'ocate. 



Last season LATi:\IER'S DRY made its introduc- 

 tory boAv to the apple groAvers of the XorthAvest and 

 met A\dth instanct success in every district Avhere it 

 Avas used. 



One large orchardist Avrites from Washington : "I 

 am more than Avell pleased Avith my results after using 

 Latimer's Dry. I have had less wormy fruit this year 

 than I haA-e ever had in all my experience and I am 

 Avilling to giA'e the credit to your lead." 



We Avant to convince a'Ou this year that in a season's 

 use LATIMER'S DRY is 



MORE CONVENIENT 

 MORE EFFECTIVE 

 MORE ECONOMICAL 



than any paste lead you have ever bought.

Influence of Pruning, Etc.

 (111 the tc'rniin;il portion of the shoot. If 

 thuse strong, potentiully spur-proclucing 

 buds were evenly distributed between 

 the basal and terminal half of each and 

 every shoot, it is evident that a 50-per- 

 cent thinning would remove exactly as 

 many as a 50-per-cent heading back; 

 but on the other hand, that if all such 

 buds were located on the terminal half 

 of each shoot the heading back would 

 remove them all, while the thinning out 

 would remove only half of them. These 

 are extreme cases, but they at least 

 serve to illustrate the general tendency 

 of the two practices so far as concerns 

 the removal of spur-forming buds. Fur- 

 ther?nore, there is an e(|ually great con- 

 trast between the results that follow 

 thinning as compared with heading in 

 the influence of the two practices upon 

 the location, or distribution, of such 

 buds upon the new shoots. Just as 

 heading back tends to increase the 

 amount of new shoot-growth, concen- 

 trate it in a smaller area, lead to crowd- 

 ing and thus through shading to a push- 

 ing out toward the end of the shoot 

 the area that produces large plump 

 spur-producing buds; so thinning out 

 tends to decrease relatively the amount 

 of new shoot growth, distribute it over 

 a larger area, avoid crowding and thus, 

 through providing better light condi- 

 tions for the basal portions of the 

 shoots, lengthen the area that produces 

 spur-producing buds and bring it 

 closer to the base of the shoot. Nat- 

 urally the eflecfs of light or moderate 

 thinning out ui)on fruil-spur formation 

 may be expected to be less pronounced 

 than those following heavy thinning. 



From the statements that have just 

 been made, if might be inferred that 

 because we desire a large number of 

 fruit spurs in the api)le tree and be- 

 cause the tendency of winter thinning 

 is to encourage their formation while 

 that of winter heading is to check or 

 reiiuce it, thinning out is the only prun- 

 ing practice to be recommended and 

 heading back is in all cases to be 

 avoided. Even though such recom- 

 mendations were made few practical 

 fruitgrowers would be inclined to fol- 

 low them, at least without some modi- 

 lieation, for they know that constant 

 thinning out coupled with no heading 

 back eventually would result in the 

 development of loose, straggling trees — 

 trees weak mechanically, even though 

 they might possess sutlicient spuis for 

 large crops of fruit. Is there not some 

 way, then, of keeping the apple tree 

 fairly comjiact and still not invite the 

 evils attendant upon the severe winter 

 heading back that is practiced so com- 

 monly? Investigations of the Oregon 

 Iix|)eriment .Station extending over a 

 number of years lead to our recom- 

 mending a certain tM)e of sunmier 

 pruning to obviate this dilliculty. It has 

 been foimd that an early summer prun- 

 ing (about .luly 1) of young apple trees 

 is followed by a secondary late sum- 

 mer-shoot growth that functionally 

 closely corresponds with the terminal 

 half or third of shoots on trees that are 

 not sinmner pruned. That is, this late
