2. Cranberry Rot. This, like the potato rot, the pear blight, the peach 

 yellows, or the hog cholera, can not always be averted. Thi.s trouble is sup- 

 posed and believed to result from de.'^tructive fungi, but how to conij)as8 the 

 ditiiculty is not so easy to answer. A general application of lime has been 

 resorted to, but not with uniform success. So far as we know, we are to do 

 what we can to promote and nothing to impair the general health of the 

 vines. 



3. The ravages of the cranberry worms, of which there are two kinds, 

 those which att;ick the vine and those attacking the fruil. The most destruc- 

 tive probably is the vine worm. Of this there are three or four generations 

 during the season. The first appearance of the miller is usually about the 

 last of April or first of May. The larv;e appear usually about the middle of 

 May, and feed ufjon the tips of the vines, eating downward, maturing in 

 about ten days. It then webs itself and lies in a chrysalid state about seven 

 days. Then the miller shows itself as before, only in greatly increa.^ed num- 

 bers. The second generation of the worm is by far the most destructive, 

 and shows strongly the importance of paying close attention to the first ap- 

 pearance of the miller in spring. It is said that three if not four generations 

 of the vine worm are produced during the growing season. In a critical, 

 accurate knowledge of this insect, its first appearance and its habits, lie the 

 security of growers. Unquestionably the power to cover the vines quickly 

 with water gives greatest security to the grower, not only against the vine 

 worm, but also against untimely frbsts. 



The other worm, or fruit worm. The miller makes its appearance in New 

 England about the last of May. In July it deposits its egg under the skin 

 of the growing fruit. The ettect on the fruit is noticed by a premature red- 

 ness, shown during the latter part of August. Each worm in about ten days 

 destroys a berry, and emerging from it, attacks another, often destroying 

 half a dozen berries. 



While this worm destroys considerable fruit, its ravages are much less 

 severe than the vine worm. The only })reventive we know is close observa- 

 tion and sudden flowage for a short time to destroy the larvje, or previously 

 perhaps to prevent the deposit of eggs. 



Perhaps enough has already been said to lead the prudent to be cautious 

 about making cranberry investments. Probable success depends, first, upon 

 having the natural conditions right, viz. : a proper soil and location, with 

 abundant living water, available and clear sand at all times, speedy drainage, 

 and in connection with these favoring conditions, sufficient capital and labor 

 and the most intelligent and careful superintendence. 



To rush headlong and at haphazard into some joint stock enterprise, of 

 which the stockholders know as little as they do of the mountains of the 

 moon, is to incur probable loss and disappointment. And yet while the fu 

 ture will, like the past, probably bring many failures in the cranberry busi- 

 ness, it will also have some grand successes. To avoid the former and to 

 secure the latter in full measure should be the aim of all cranberry growers.
