feed more or less on the underside of the foHage as they make 

 their way toward the apple, and inasmuch as nearly 20 per 

 cent of the worms which reach the apple will attempt to enter 

 through the sides, it is necessary that both fruit and foliage be 

 thoroughly coated at this time with a poisonous mixture. In 

 view of the further fact that fungous diseases of one sort or 

 another are always with us, it seems advisable to use a fungi- 

 cide as well. 



The mixture should in this case be the same as that recom- 

 mended for the fourth treatment, and a special effort should be 

 made to coat the under and upper sides of the leaves and all 

 portions of the fruit with the material. The mixture should be 

 applied as a fine mist, because in this way the most complete 

 coating possible can be obtained. The machinery here is the 

 same as in preceding treatments, and needs no especial con- 

 sideration. 



Sixth Treatment. 



Eight or nine weeks after the blossoms fall the second brood 

 of codling moth worms begin to enter the apples, and the 

 coating given the trees five or six weeks before has almost 

 entirely disappeared. Furthermore, the protection against 

 fungous diseases has likewise gone with the disappearance of 

 this coating. It is therefore necessary at this time that the fruit 

 and foliage be recoated, the foliage primarily from the stand- 

 point of protection from leaf feeders and fungous diseases, and 

 the fruit from the standpoint of protection from the apple 

 worm. The material used in this treatment should be the same 

 as that recommended in the previous treatment, and it should 

 be applied as a fine mist, with an especial effort to give to the 

 foliage (particularly the upper side) and the fruit (all sides) a 

 complete coating consisting of fine specks of the spray material. 

 The machinery question is here the same as in the preceding 

 treatments, and does not require especial consideration. 



Special Treatments. 



The apple maggot, or railroad worm, will probably in most 

 cases, at least where clean orcharding is practiced, be taken 

 care of by the above-outlined treatments, the flies being poi-
