orchard, I am specially happy to explain and commend it 

 to you. The old band method was utterly impracticable. 

 It required labor and attention just when the tension of the 

 busy season was at its height, and so the remedy failed, for 

 want of needed labor and attention. 



The far better hay remedy is only complete when the 

 *' wormy apples " are all felled to the ground. This labor .of 

 thinning is often very richly rewarded, in the finer fruit se- 

 cured because of thinning. Yet, as with the labor of remov- 

 ing the bands, it is apt to be neglected, and thus the remedy 

 fails to give satifaction. Again in seasons of scarcity, when 

 fruit is money, and when from the very nature of the case. 

 Codling larva will be the most destructive, this remedy is 

 only locking the stable door after one horse is stolen in 

 hopes to save the other horse. At such times, when both 

 horses are so valuable, the mere saving of one is far from 

 satisfactory. 



The use ol the arsenites Paris green or London purple, 

 saves both horses and is a cheap and easy way to accomp- 

 lish this important work. My experiments, which have 

 been elaborate and have extended over several years, estab- 

 lished several points: First and most important these arsen- 

 ites kill the insects before they enter the apples and so the 

 fruit is preserved sound and beautiful. Secondly, it takes a 

 surprisingly small amount of the poison to sound the death 

 knell of the insects. The faintest trace of these arsenites 

 always kills, and thus we should be thorough in our appli- 

 cation; but use a very dilute admixture. Again the moth 

 is even waiting for the blossoms to open, and so the fatal 

 egg is often laid before the blossoms have fairly fallen from 

 the trees; therefore we must apply the death dealing potion 

 very early, before the young fruit is larger than a two-grain 

 quinine pill. Here is where some have partially failed in 

 the use of this remedy. They have waited till the larva 

 has hidden within the green pulp, and is safely out of harm's 

 way. I would not make the mixture stronger than one 

 tablespoonf ul to two gallons of water. Were I to modify this 

 at all I would make it weaker. To spray an orchard the bar- 

 rels should be drawn in a wagon, and so fastened that they
