were sprayed with arsenate of lead in 1002, sucli excessive rains fell 

 tliat no conclnsive results were obtained. lUit last season similar 

 spra^'iiig experiments witli arsenate of lead (4 {)()unds in 50 gallons of 

 waj;er) gave some very promising results. In one vnneyard three plots 

 of vines gave the following striking resnlts: On the unsprayed vines 

 the leaves were badly eaten by the beetles, and on 10 vines 97 egg 

 clusters were found ; on vines sprayed once the foliage was but little 

 eaten, and only 7 egg clusters were found on 10 vines; one plot 

 was spraj'ed twice and there were scarcely any signs of the foliage 

 being eaten, and a careful examination revealed but 1 egg cluster on 

 10 vines. These are certainly astonishing results, but the spraying 

 was thoroughly done, and there is scarcely a chance that any peculiar 

 conditions could have influenced the results when the plots were prac- 

 tically side by side in the same vineyard. Furthermore, another reli- 

 able vineyardist in another town who sprayed a large portion of his 

 vineyard but once feels very sure tliat he acconiplished much toward 

 controlling this destructive pest, and an examination of his vines in 

 comparison with a neighbor's across the road gave very encouraging 

 results. Further spraj'ing will be done next season in a vineyard 

 into which a swarm of the beetles migrated and fed extensively last 

 summer from a badlj^ injured vineyard across a meadow 30 or 40 rods 

 away. This migration of the beetles in a body from one vineyard 

 into another thrifty one affording better pasturage for themselves and 

 their grubs later is a new and very alarming fact, for it means that 

 the best-cared-for vineyards are constantly menaced by neighboring 

 infested vineyards where no fight is being made against the pest. 

 Doctoi- Felt has captured thousands of tlie beetles in a "catcher," 

 designed to be di-awn along on each side a row of vines. Other Jiand 

 "catchers" have been devised, but most vineyardists are waiting for 

 a more conclusive demonstration of the elfectivenessof this laborious 

 method before they will put it into practice. 



Mr. P. J. Parrott informs me that this rootwoi-m, which has devas- 

 tated Ohio vineyards for several years, is now in its "down" or non- 

 destructive period and is comparatively scarce in the infested region. 

 There are some indications that it is also disappearing as a pest from 

 the earliest-infested region in Chautauqua County, N. Y. 



An outbreak of that common grape pest, the grape leaf-hopper, 

 unprecedented in extent and destructiveness in the annals of New 

 York, has occurred in nearly the same region infested by rootwoi-ms 

 in Chautauqua County during the past three years. INIore than a 

 thousand acres of vineyards have been infested to the extent tliat 

 the vines did not make growth enough to furnish sufficient wood to 

 tie up for the next season's crop, and the foliage was often killed in 

 eai'ly fall, and thus the proper coloring and ripening of the fruit and 

 wood was prevented. No vines were killed, but it will be two or 

 three years befoi'c many vineyards regain their normal vigor. After
