INSECTS INJURIOUS TO THE CEAKBERET. 135 



infested vines several times after taking the water off in 

 the spring. The water should be put on every ten days 

 during the month of May, and allowed to remain ten 

 hours. This treatment allows the eggs to hatch, and 

 the young worms are quickly drowned. Where water is 

 scarce, defer flowing until late winter, thus exposing the 

 eggs to severe cold, which is thought to destroy them.* 



The " Scald " oe Eot. 



In an essay on this subject Mr. J. A. Penwick says : 

 " When Cranberries on the vines are softened and become 

 semi-transparent, or like partly cooked berries, it has 

 become common to say that they are "scalded." This 

 softening does sometimes result from water covering 

 them, and becoming hot and stagnant, but it generally 

 occurs in a dry time, without water, and it is a misnomer 

 to call it a scald. This roasting, rather than scald, 

 which has destroyed the crop of berries so very much for 

 a few years past, has been most destructive at the time of 

 gathering the crop, or shortly before, the fruit as it ap- 

 proaches ripening being more sensitive to a high tempera- 

 ture. Only in extreme cases do large spaces in August, 

 or before that, become generally softened while they are 

 yet green, but have obtained some size. The effect of high 

 heat is to produce spots in the fruit, the inner structure 

 being disorganized, as shown by transparent spots, which 

 grow larger on a repetition of the heat, particularly in 

 muggy, wet weather, either on the vines or after being 

 picked ; but some fruit in fair weather will dry up and 

 the rest of the berries remain sound. 



" The effect of high temperature, when the fruit has 

 but just formed, or until it is of some size, is to dwarf 

 it, leaving it at picking time but little larger than it was 

 when the blossom dropped from it.
