much more destructive than its American ally. In size it is ahout the same as 

 the preceding, but in color it differs, being yellow with a black head. The larva 

 of this saw fly is green covered with black dots until the last moult. It then 

 becomes entirely green, and is about half an inch long. They destroy the 

 leaves by eating them full of small, round holes. The eggs are laid on the 

 under side of the leaves. The larva spins its cocoon in the rubbish at the base 

 of the bushes and there changes to its perfect form. 



The best remedies for both of these slugs are the same, viz. : sprinkling them 

 with pretroleum or with a solution of whale oil soap, or with white hellebore, 

 either powdered or in solution. All of these will be apt to injure the fruit. In 

 case of the foreigner we may many times discover and destroy the leaves with 

 eggs on them. 



The currant worm is the young of a yellowish moth whose wings are spotted 

 with black. There are also rows of black spots on the body. The worm is 

 covered with black dots and is about an inch long when fully grown. It has 

 but ten feet, and is one of the so called "measuring worms." It goes just be- 

 neath the surface of the soil to pupate. The eggs are laid on the twigs of the 

 bushes in the fall, and remain there until just as the leaves are coining out in 

 the spring, when they hatch and commence eating. As the clusters of eggs are 

 white we may destroy them in the winter season. If this is not done the worms 

 may be shaken off and killed or destroyed by sprinkling with petroleum, white 

 hellebore, or a solution of whale oil soap. 



Leaving those insects which feed upon the currant, let us next notice a few 

 •of those which feed upon the cabbage and allied plants. First of these are the 

 ■cabbage worms, of which we have three kinds in this county, but all are much 

 alike and are destroyed in the same way. None of them are confined to the 

 cabbage, but feed also on the turnips, ruta baga, cauliflower, and many other 

 similar plants. 



Those pretty white butterflies which we so often see flying about in our fields 

 in spring and summer are the parents of one of these worms. The larva of 

 this white butterfly is about an inch and a half long when fully grown. It 

 suspends itself by the tail on the under side of old sticks and boards when about 

 to change to the perfect form. The eggs are usually laid on the under side of 

 ;the leaves. 



We have two broods of them, the first appearing in the latter part of May or 

 early in June and the second in August or later. 



The spotted cabbage butterfly differs from the preceding chiefly in having 

 ■ several large irregular black spots on the wings. Its larva is green spotted with 

 black. Both of these are quite abundant here and may be seen every season. 



The parent of the third one of these cabbage worms is the foreign cabbage 

 butterfly. The female of this species has two round black spots on each wing. 

 Tin' larva is green, and is very destructive. It is rather curious but very vex- 

 ing to us to see how much more voracious and destructive these foreign insects 

 are here than in their native country. 



A very good way to lessen the numbers of these cabbage worms is to place 



boards about an inch above the ground among the cabbage plants. They will 



.attach themselves to the under side of these to undergo their transformation 



and may then be easily destroyed. Catching the few butterflies in spring when 



they fust appear will go a great way in protecting the plants. 



Our cabbage and tomatoes are badly injured many years by being eaten off 

 just above the surface of the ground. This is the work of the well known cut-
