REPORT OF THE HORTICULTURIST. 113 



the entire tree would bear the peculiar tufted broom-like growths. The twigs were 

 always abnormally thickened by the shortening of the internodes and the close packing 

 together of the buds. Affected trees are not known to recover ; growth is greatly 

 retarded and such trees are usually barren. As the disease Peach rosette (whose life 

 history, like the yellow's, has never been worked out) is peculiar to the south and 

 unknown here, specimen twigs taken from these trees were submitted to Dr. Edwin F. 

 Smith, Assistant Pathologist U. S. Dept. of Agriculture, Washington, D.C. Dr. Smith 

 writes under date of July 8, that " the txifted shoots somewhat resemble rosette, but I 

 do not like to pronounce it such. If it is a genuine rosette, the limbs bearing such 

 growths will die this fall, or be dead next spring." In answer to further letters on 

 the subject he writes on August 8, that " the samples sent are not affected with 

 rosette." This is satisfactory as far as the disease known by that name is concerned, 

 but the form so much resembling it at Olinda and Leamington appears to be as much to 

 be dreaded. Not only do trees attacked, not recover, but a single specimen appears to 

 act as a centre from which the malady spreads slowly throughout the orchard. 



Remedial. — While true rosette has not been found in the northern peach-growing 

 states it is to be hoped that we have not already a form equally injurious. In view of 

 this possibility, peach growers should not hesitate to remove promptly trees that show 

 symptoms of the presence of this obscure enemy. I am pleased to state that through the 

 intelligent and energetic efforts of Mr. Bruner (fruit tree inspector) fruit growers in the 

 neighbourhood of Olinda are amply warned regarding the gravity of the case and the 

 necessity of instituting radical preventive measures. I regard this enemy as one of 

 the most serious affecting the peach interests of the western peninsula of Ontario, and 

 fruit growers are urged to apply the most heroic treatment possible when these rosette- 

 like growths make their appearance. The mere removal of the affected branch is not 

 sufficient ; the tree must come out root and branch. 



▲ SERIOUS GRAPE TROUBLE. 



For a number of years — six or seven or more — grape growers between Hamilton 

 and Niagara Falls have noticed here and there in their vineyards unthrifty and sickly 

 looking vines. In some instances the trouble would be confined to a few vines occupy- 

 ing a small area. Again it would be more or less scattered throughout the vineyard. 

 It was brought to my notice in the summer of 1896, by a letter, accompanied with grape 

 foliage, forwarded by Mr. W. M. Hendershott, St. David's, Ont. Early in June of the 

 same year, Mr. L. Woolverton, of Grimsby, forwarded a vine similarly affected, and on 

 26th June wrote as follows : — 



Grimsby, 16th June, 1896. 



Dear Mr. Craig, — I received your letter regarding the affected grape vine, and 

 since that time have been examining the vine more particularly, root, branches and 

 leaves, but have not yet been able to discover any cause for the peculiar disease. To-day 

 Mr. L. Hagar called me in to see his vineyard, and I found that it was sadly affected 

 with the same trouble. He has a large vineyard, and in it there appear to be at least 

 two or three hundred vines that are dying, because of the disease. It appears to be 

 spreading. Last year it began with a few vines of Moore's Early, which were destroyed 

 by it, and this year it has extended as I have stated above. Evidently it is a very 

 serious trouble, and requires immediate attention, or the whole vineyard will be 

 destroyed. Strange to say, it is mostly the Concord which is affected with him, a 

 variety which is seldom infested by Phylloxera. I have dug up a whole vine in Mr. 

 Hagar's vineyard, and forwarded it to you by mail, so that you may have it carefully 

 examined. Please do this and send me your reply as early as possible, in order that we 

 may know what treatment to give our vines. 



I am, sir, 



Yours very truly, 



L. Woolverton.
