THE WORM AND THE ROT. 283 



than one season with the vine-worm, while the other has escaped 

 entirely. 



3. The other worm from whoso depredations the cranberry 

 bog suffers is known as the fruit-worm or berry-worm. The 

 miller is first seen about the 25th of May. Towards the middle 

 of July it deposits its egg under the skin of the growing fruit. 



The worm makes its appearance in the berry during the last 

 of August. Its presence is shown by a premature redness of 

 the fruit. In about ten days he destroys the berry and emerges 

 from it, and passes into another. One worm will destroy 

 perhaps half a dozen berries. Then in the early part of Septem- 

 ber, it goes into the ground and lies in a chrysalid state until 

 about the 25th of May, when it appears again in the form of a 

 miller, as before stated. Although this worm destroys the fruit 

 to a considerable extent, its depredations are far less serious 

 than those of the vine-worm. Indeed, I have heard cranberry 

 growers say they cared very little about the fruit-worm. When 

 they destroy a portion of the berries upon the vine, the remain- 

 ing ones grow to so much greater size as to compensate in a 

 considerable degree for the loss of those which they take. 



The remedy in the case of the berry-worm is to flow the bog 

 after he has eaten out of the first berry, and is exposed to the 

 effects of the water. This worm resembles the vine-worm in 

 size and form. Its color is white with a yellowish tinge, and its 

 head is red. 



4. Another obstacle in the way of cranberry culture is the 

 rot, which is observed about the first of September. Until 

 within a few years no great trouble has been experienced from 

 the rotting of the berry, but it now constitutes a peril of a good 

 deal of magnitude in the way of the cranberry grower. And it 

 threatens to be as destructive as the worm or the frost. In the 

 season of 1865, Cyrus Cahoon, of Harwich, one of the most 

 extensive as well as one of the most intelligent cranberry grow- 

 ers of Barnstable County, had a fine lot of growing cranberries 

 estimated at eight hundred barrels. The berries were however 

 invaded by the rot, and only 171 barrels out of the 800 were 

 saved. 



This form of injury to the crop is comparatively recent, and 

 as yet no method has been devised to prevent it. Cranberry 

 cultivators are not agreed as to the cause of the rot. Dr.
