32 SPRAYIXG THE APPLE ORCHARD. 



and much was otherwise blemished. A record of the 

 number of barrels of Xo. 1 and No. 2 fruit from both 

 sprayed and unsprayed trees was kept, and showed that 

 3 1-5 barrels were secured from each sprayed tree, against 

 1 4-5 barrels on each of the unsprayed trees, or a net gain 

 of 1 2-5 barrels, worth $1.40 net. Deducting from this 

 the cost of spraying, Ave have a net profit of around 

 $1.25 per tree as the actual profit. Had the orchard been 

 well fertilized and cultivated so that the trees could have 

 matured the large crop they bore, as full size apples, a 

 profit of over three dollars per tree would have been act- 

 ually realized. This shows that spraying is but a part 

 of successful apple culture, and that to secure the greatest 

 profit from it, the orchard must be well cared for otherwise. 

 Even larger profits may be expected where fruit of the 

 best size and quality is grown, for in our experiments in 

 Delaware orchards in 1901 and 1902^ we showed that two 

 to three barrels more non-wormy fruit might be picked 

 from sprayed than from unsprayed Winesap trees, prac- 

 tically all of which fruit was No. 1, and that year brought 

 about $3.00 per barrel net, thus giving a clear profit of $6 

 to $10 per tree from the spraying, equivalent to $2.50 to 

 $3.75 for the same amount of fruit at the price usually 

 received for New Hampshire Baldwins. 



Comparing the results secured in the different orchards, 

 which are a fair average of those throughout southern 

 New Hampshire, we see that at the average price of winter 

 apples a net profit of from $1 to $1.35 per tree may be 

 secured from two sprayings solely from the effect upon the 

 codling moth, for in all the above estimates no considera- 

 tion has been given to the effect upon scab, brown spot, 

 rots, etc., Avhich will he mentioned below. Indeed, with 

 proper care of the orchard, this profit from spraying alone 

 should be at least trebled. Why, then, do you not spray? 

 Possibly one of a thousand would-be excuses which seem
