operations. Mr Clymonts's observations led him to think that as 

 a rule the younger vineyards, specially those planted in the last 

 10 or 12 years, suffered most, and that the old ones escaped with 

 comparatively little harm. The most destructive work observed 

 by him had been on sandy soil, or on ridges in other pieces. He 

 also stated that vines set in an infested vineyard to fill vacancies 

 do not thrive and are usually killed by the insect. A recent com- 

 munication, Aug. 27, 1903, states that nothing has developed the 

 present year to make it advisable to modify any of the above 

 statements. 



Mr J. W. Maxwell of Euclid stated in 1902 that 50$ of the 

 vineyards were dead in that section, and that in his opinion a 

 large proportion of them died as a result of the operations of this 

 insect. His crop of grapes in a large vineyard was reduced 

 fully one fourth, the most of which he attributed to this pest. 

 He stated that the Wordens and Erightons were killed first, 

 while the Concords and Catawbas were not so badly injured. 

 He also adds, in a letter dated Aug. 29, 1903, that renewing a 

 vineyard with Niagara vines seems to be quite a success, since 

 800 roots set two years ago in vacancies all lived and have done 

 well. We hope this will continue to be the case, but in the 

 writer's opinion these recently set vines have just reached a very 

 attractive condition, so far as the beetle is concerned, and he is 

 afraid that injury may result in a year or two. 



Mr W. H. Slade of East Cleveland estimated in 1902 that one 

 fourth of the vineyards in that section had been destroyed by 

 this insect pest, and according to his observations the Wordens 

 and Catawbas suffered more than the Concords. The most seri- 

 ous damage in his experience was met with on the lighter soil of 

 knolls. 



Mr W. W. Dille of Nottingham was of the opinion in 1902 that 

 there has been a decrease in recent years of 40$ in the area 

 devoted to grapes. He attributed this shrinkage about equally 

 to the rot, which had been very prevalent, to the operations of 

 the grape root worm, and prevailing low prices. He stated that 

 the insect injuries had been limited mostly to the bluff and to 

 vineyards in the near vicinity of the lake shore, those back and 

 just under the bluff escaping with comparatively little damage. 

 He considers the Concord as one of the most resistant varieties.
