two kinds. The most destructive is that which is known as the 

 vine-worm. The first indication given of the presence of this 

 worm is about the latter part of April, when, by careful obser- 

 vation, a small miller is discovered about the cranberry bog. 

 This miller punctures the fruit-bud and lays its egg within it, 

 and having been visible about ten days, disappears. Then, in 

 warm localities, the larva makes its appearance in the bud 

 about the fifteenth day of May. At first it is hardly discernible, 

 but it feeds upon the bud and the vine and grows rapidly, and 

 in about ten days comes to maturity. It then webs itself up 

 and lies in the chrysalid state for seven days. Then the miller 

 shows itself for ten days, lays its egg, and disappears as before. 

 This generation appears in comparatively small numbers. They 

 inflict no material injury upon the vine. But about two weeks 

 after the disappearance of this miller — and this is in the last 

 part of June or first of July — the larvos.of the next generation 

 make their appearance upon the vine in great numbers, and for 

 the ensuing ten days their ravages arc very great. The worm 

 begins at the top of the vine and eats downward, destroying the 

 blossoms and the new growth of the vine. When they are very 

 numerous they feed also upon the growth of the previous year. 

 From the tenth to the fifteenth of July his career is ended, and 

 he passes into the chrysalid state to appear again in due time. 

 It is said that three and perhaps four generations of this 

 worm appear during the season, showing themselves on the bog 

 as late as October. The vines, however, do not suffer from 

 them to any appreciable degree at any time except during the 

 early part of July. The only method of protecting the vine 

 against this worm is by flowing. When the water is kept upon 

 the vines until the first of June the generation of the worm is 

 prevented, and so far as he is concerned the crop is safe. This 

 worm bears a resemblance to the apple-worm. Its color is light, 

 with a bluish tinge, and its head is black. It is about three- 

 eighths of an inch in length when fully grown. The miller 

 appears to be somewhat longer, is of a gray color, and has a 

 white stripe across the back. It flies but a short distance, 

 usually not more than a foot at a time. There arc two bogs in 

 the town of Dennis lying close together, being separated only 

 by a road that runs between them, the vines running to the ruts 

 on either side. Yet one of the bogs has been infested for more
