SULPHUR sCURE, AS APPLICABLE TO THE VINE DISEASE IN AMERICA, AND DISEASES OF APPLE AND OTHER FRUIT TREES. By WILLIAM J. FLAGG, AUTHOR OF ‘‘ THREE SEASONS IN EUROPEAN VINEYARDS.” NEHW YORE: HARPER & BROTHERS, PUBLISHERS, FRANKLIN SQUARE. 18,70. C~ * Entered, according to Act of Congress, in the year 1870, by HARPER & BROTHERS, In the Clerk’s Office of the District Court of the United States for the Southern District of New York. ee PREFACE. AC the request of many vine-growers* who had become acquainted with my completely suc- cessful treatment of “mildew” by the sulphur-cure as learned in Europe, I undertook to set down a few brief precepts and rules for the guidance of such persons as might be disposed to follow my example. The work has grown into something like a treatise, and become much larger than I at first proposed to make it; and yet a good deal is omitted that might, perhaps, profitably be included, because I have thought it prudent to wait and observe for one or two seasons more, and also collect the obser- vations and opinions of others, whose co-operation I now solicit, before attempting to write a work that shall cover the whole ground. And I here give no- tice that I write as a learner rather than a teacher, and reserve the right to confess my errors as often as I shall become aware of them. ty. PREFACE. Thus premising, I venture to affirm that the need for this little work is most urgent. So far as I have, with diligent inquiry, been able to learn, the meth- ods for sulphuring diseased vines at present known to the grape-growers of America (except only as em- bodied in my lately published work on European Vineyards) are wholly insufficient, and can, in our cli- mate, lead to nothing but failure and discourage- ment. The reasons for this will be developed in the - pages which follow. CONTENTS. CHAPTER I.
