prerentive. Mr. L. tlionght the blight might be caused by the sudden 

 changes of temperature from cold to liot, especially after a shower. 0. H. 

 Wigglesworth said iu Xew Hampshire they used salt sea weed as a mulch for 

 their trees, which was a great benefit to them, causing the apple trees to make 

 a luxuriant growth. 



Captain Bunnell said the blight commenced on the end of the limb, usually 

 the terminal shoots, and in a lew hours it will turn brown, continuing to die 

 back a foot or two. Different cultivation made no difference, though he 

 thought some varieties more liable to it than others. 



W. H. Iliirlbut differed with him. He could see no diflference in different 

 varieties, nor different thrift, farming, soil, or culture. He attributed it to 

 insects. He had studied it carefully when it appeared seventeen years ago in 

 his orchard at Bangor. He would recommend cutting off all the attected 

 limbs at the first appearance of it, cutting off all this year's growth from the 

 affected limb. 



Alfred Fitch had found a small worm at the commencement of this year's 

 growth on a limb beginning to blight. 



W. H. Hurlbut said the blight generally occurred after the worm had left. 



The secretary made a careful examination of the limbs brought in — one from 

 a Golden Kusset tree, one from a Greening, and one from a Transcendent 

 crab, and in all, at the commencement of this year's growth, a small hole was 

 found through which a worm had crawled out, and on cutting open the wood 

 a small discolored hole was found in the pith of the limb. It was suggested 

 that a blighting of the limb would cause a shrinking in the pith ; but limbs 

 subjected to an oven temperature of ICO degrees turned brown in a few min- 

 utes, but produced no holes in the pith, which is quite hard and firm at this 

 season of the year. The probabilities are that an insect lays an egg in the 

 terminal bud early in the spring, which hatches out and eats the pith during 

 the growth of the shoot. When the worm completes its growth it eats out and 

 falls to the ground to transform into the winged state. The worm, in coming 

 out of the limb, lets the air into the cavity, which causes it to discolor, decom- 

 pose, and check the circulation of sap, which in bright, clear, warm days causes 

 the limb to blight. There may be blight in the apple similar to pear blight or 

 frozen-sap blight, but we have not seen it yet. 



Master L. H. Bailey showed ajar of fall web worm ou an apple leaf. 



THE YELLOWS. 



South Havex, Aug. 22, 1874. 



A large attendance was present at the Pomological Hall Monday evening. 

 The table was graced with eleven plates of apples and pears from T. T. Lyon's 

 orchard, at Plymouth. Special attention was called to the Garden Eoyal apple 

 and Sterling pear, which Mr. Lyon said were very valuable varieties of fruit, 

 and would command a high price in market when known. He would recom- 

 mend care in growing, thinning and picking, packing and labeling new and 

 choice varieties of fruit, which would improve the standard and price. 



The Committee on Yellows made the following report :
