Bring these together in the order in which they are named, 

 adding the Paris green last, stir thoroughly, and spray the 

 plants. Do not prepare the spraying solution mixture, how- 

 ever, till ready to use it, as it settles on standing. 



This treatment has been used with good success, and with 

 reference to it the following statements are made : first, that 

 by it late cabbage and cauliflower can be protected from the 

 attacks of the cabbage worm and cabbage looper by two 

 sprayings ; second, that in the case of cabbage the yield can 

 be increased sixty to one hundred per cent ; third, that the 

 cost per acre will depend on the number of acres sprayed, 

 the cost of spraying ten acres twice being twenty dollars ; 

 fourth, that the mixture must not be applied to cabbage after 

 the heads are two-thirds grown, nor to cauliflower after the 

 " flower " appears ; fifth, that only skilled workmen should 

 be permitted to spray cauliflower. 



In view of the amount of work necessary to prepare this 

 mixture, and the amount of care necessary, as indicated by 

 these last two statements, it becomes questionable whether 

 the advantage gained by using it — a more thorough adher- 

 ence of the spray to the leaves — is sufficient to pay for the 

 extra expense and trouble. In any case, it is most likely to 

 be of value where the acreage of cabbage is very large. 



The Squash Bug (Anasa tristis DeG.). 

 The squash bug is a familiar insect in this country on 

 squashes, melons and other cucurbits. The adult bugs pass 

 the winter in any protected places they may find, and in the 

 spring, after the squashes are well up, lay their 

 eggs on the under side of the leaves. The 

 eggs are light reddish-brown in color, and very 

 noticeable on the leaves. They hatch in a 

 little more than a week, producing small 

 green-and-black young, somewhat resembling 

 the adult, but without wings. These young Fu^4.-8qua'lh 

 keep quite close together on the under side of ^ug: nduit bug,

 the stems, all the time sucking the juices from the plant. 

 They feed in this way and grow for about a month, the in- 

 sects changing in appearance from time to time as they throw
