kmpfdoms hnvo niaiiy c-liaraffcrlstifs whicli arc aiialii,i::;mis. Do wc know 

 that sulpliur tims iiitroiliict'd will not so afi'ect tlie tiet; as to prevent dis- 

 ease, as the writer state's ? 



Mr. John G. Berg;en.— This matti^r must be settled by experimental facts 

 and nttt by tlKviry, and it must be by a series of exjioriments — (jiit; never 

 determines a f^et. Theiv is a p;entleman present who states to me that he 

 has tried tJie exjK'riment \A' pluj^j^ing' sulphur iji cherry tre<?s, and it pro- 

 <luced rut cflevt. But that does not disprove the fact stated by the g'entle. 

 inan that suipliur did apparently cure the jiear blight in North Carolina. I 

 wish Uv liad stated v»liether it was the summer or winter blight, for they 

 are distinct and their ellect very different. The progress of the winter 

 blight is sometimes very slow, while that of the summer blight is often so 

 raj>id that the tives are often past recovery bcf<H-e the disease is discovered. 

 Tiic best reuKxly for the winter blight is to carefully prune off all the limbs 

 d»twn to t]ie sound wooil. The same remedy might be applied to tiie sum- 

 mer blight if discovered in time 



Mr. Win. S. Carpenter. — I should like to know how a remedy could be 

 applied to such a bliglit as swept over the country this year, withering the 

 leaves upon one side (jf all the trees in an orchard in one day, indeed, almost 

 instantly. I believe the ordinary winter blight, common all over the 

 United States, is caused by strong growth and immature wood suddenly 

 frozen in autunin. The cause of the summer blight is less certain- it affectp 

 large and small trees alike. 



Mr. Wm, R. Prince. — I believe the cause of summer blight io as much 

 atmospheric as that of winter blight. It appears to be caused by intense 

 beat upon vigorous branches. The most vigorotis growers, such as the 

 Madeleine and White Doyenne, have been more affected than others; that 

 is, in our vicinity. The Bartlett produces much immature wood, and is 

 more apt than others to be aff«'cted by winter blight. It was the practice 

 <if my father to cut the trees down some ten or fifteen inches below where 

 the tree was affi-cted. I do not remember losing one. 



Mr. K. (}. Pardee. — The blight whiLh has been most common in Western 

 New York does not attack and destroy suddenly, but may be seen first 

 upon one leaf (.n the end of a twig, then upon another and another, gradu- 

 ally wcuking its way down, and during the summer a long portion of the 

 shoot will be found to be dead. If, as Mr. Prince recommends, the limb is 

 cut off below where it is aflectcd, the tree, in all probability, will be saved. 



Gas Lime. 



Mr. Marcus Spring, Perth Amboy, N. J., asks: " IIow, and to what 

 xtent, arc the fertilizing ipialities of lime affected by its use as a pinifier 

 fcoal gas f Plea«e also say what is the best mode of using gas linii! as 

 I fertilizer." 



.Mr. Solon Robins(»n. — This f[uestion has been repeatedly answered in the 

 discussions of this Club; I suppose it must be again. Experience, I believe, 

 has invariably proved that gas lime is injurious to crops. I will ask Mr. 

 I'arllett, who is better authority in this matter than I am, to state the rea- 

 son wh}*. 



Mr. George Bartlett said: It is because the lime becomes charged with
