It is gratifying to know that competent vineyard-ists are confirming the results of professional experimenters concerning the almost wonderful efficiency of Bordeaux mixture for some of the diseases of the vine. Many tests were made in commercial vineyards last year, and a number of good reports have been made of some of them. Mr. David Al-lerton, a painstaking Hudson River viticulturist, gave a valuable paper upon the subject before a Farmer's Institute held at Poughkeepsie late in February. The paper was the result of actual investigation. Its main points are given below.

The grape vines treated by me with the Bordeaux mixture comprised my whole vineyard, and as some varieties up to this year had been healthy, they were on that account not treated till mildew and rot had already showed itself, but even they show the good effects of the copper solution, as it controlled mildew and brown rot even after it started, preventing further infection. The vines first treated by me were 100 Duchess and 50 Dela-wares, and my experimental vineyard, containing some 80 varieties of grapes, all of which were treated five times. With two exceptions, all of the vines remained healthy in foliage and fruit, which ripened as perfectly as any grape vine could in such a cold, wet season, The two exceptions noted were the Centennial and Mammoth Pearl. On the 26th of June I noticed that these vines were badly mildewed, the clusters, leaves and young shoots being covered with powdery mildew to such an extent as to give them the appearance of being covered with flour. I also observed that on the Duchess and many other varieties, the spores of the black rot fungus were numerous on the foliage. I procured the Bordeaux mixture and applied it to these vines - the Duchess experimental vineyard, and 50 Delawares. The Centennial and Pearl were hopeless cases.

The Delaware first treated did not lose a leaf and ripened every berry with good foliage and well ripened wood. I examined my Duchess and found, principally on vines that had had black rot the year previous, some black rot. I picked off the rotten berries and applied the Bordeaux mixture again and subsequently applied it at intervals of two weeks, picking all the rotten berries from the stem. I secured in all from the 100 vines about one quart, the fruit ripening in good order. The vines were healthy and held their foliage well.

About June 1st I noted the appearance of brown and black rot on those grapes comprising the bulk of my vineyards, Concords, Wordens and Pocklingtons, and mildew on the leaves of the Delawares, and mildew, brown and black rot on the Brightons, which last went so fast as to become a total loss. Wyoming Red and Champion were very slightly affected. Determining to do what I could so late in the season, I sent at once for an Eureka sprayer, realizing that although I might be too late to accomplish much this season the experience might be of benefit another year. I received the sprayer July 13th, which was about the time of the most severe visitation of rot. I immediately applied the mixture to all my vines in the most thorough manner, repeating it after an interval of one week. The rot on the Concord and Wordens was mainly brown rot, and some occasional vines were badly diseased with black rot. The effect on the brown rot was to stop it where it was, and those grapes not affected ripened. The increase of black rot was checked. The rot on the Pocklington was black rot, and one week after the last application I had the rotten berries picked from 500 vines. The vines were heavily loaded and would have required severe thinning had the rot not injured the vines.

However, as it was, they yielded an average of 8 lbs. to a vine.

There was some subsequent rot, but not serious. The Delawares were lightly mildewed when the mixture was first applied, and it seemed to increase greatly, so that I despaired of saving the vines, but after the second application it was checked, and the third time I sprayed with a solution of carbonate of copper, recommended to me by Col. A. W. Pearson, of Vineland.N.J. As this solution did not show on the fruit, he regarded it as equal to the Bordeaux mixture. From the 900 Delaware vines I marketed 92½ per cent. of the actual grapes on the vines which were well ripened and colored.

The machine I used was the Eureka sprayer, made by Adam Weaber, of Vineland, N. J. It is made throughout of copper, very strong and durable, and is carried on the back like a knapsack. Its capacity is six gallons, and it weighs 64 lbs. when filled. One filling will spray from 75 to 100 vines in full foliage on both sides. I easily sprayed 1,500 vines per day. The spraying tube of this sprayer beeng held low, the spray strikes the vine from beneath and on a level. It is much more effective than where a pump is used in a wagon, which application of the mixture is very unsatisfactory. My experience in the use of these copper solutions show that the spraying must be thorough to be effective. Where the mixture is thrown on with force and in a stream, as from a syringe or pump, it sticks to the clusters and will render them unsalable. Although spraying so late as the 26th of July, I had no trouble from this cause. Hereafter I shall use the carbonate of copper solution. The cost of spraying one acre, 4 times, counting labor at $1.50 per day, is with the Bordeaux $4.50 and with carbonate of copper $3-50. H.S. C.
