tbe present time, and having made a careful study of the peach for 

 nearly twenty years, can say positively that many of the trees were 

 badly diseased with the "yellows," notwithstanding the statement by 

 parties not conversant with the facts, " that it was doubtful if the 

 true ' yellows' had made its appearance in this section at that time." 

 Many visitors familiar with the disease also pronounced it the typical 

 " yellows." 



The results of Professor Goessmann's experiments made in 1875 

 as well as those of the writer, who carried out most of the details of 

 the field work of the above experiments, proved conclusively to us 

 that the disease is curable, many of the diseased trees having been 

 restored to health and borne several crops of perfect fruit. 



The causes which are productive of this disease we believe to be 

 as follows : — 



FOOD SUPPLY. 



1. In almost every case investigated, where the trees are neglected 

 and the food supply is small, the trees soon die : many of them show- 

 ing unmistakable signs of the yellows, while where the food supply 

 is abundant and of a kind suited to perfect development, the growth 

 is vigorous and healtliy, and the trees live often from fifteen to twen- 

 ty years. 



Too large an amount of nitrogenous manure, especially if applied 

 so that the trees do not get the benefit of it early in the season, results 

 in a late, immature growth of wood that is often seriously injured by 

 cold during the winters, and this is followed the next season by signs 

 of the yellows. 



The fertilizers that will be found to produce a very vigorous yet 

 healthy growth are, equal quantities of muriate of potash and nitrate 

 of soda with about four times the weight of fine ground bone, ap[)lied 

 in March or April, from 5 to 10 lbs. to the tree, according to size. 

 Wood ashes, 5 pounds, ground bone, 2 pounds, with from i to 1 lb. 

 of nitrate of soda to each medium sized tree will also prove very sat- 

 isfactory. If the land is poor, containing little organic matter, a 

 liberal dressing of stable manure may be applied in the fall, but if 

 the land is not -uer?/ poor, chemical manures will give better results. 

 All manures or chemical fertilizers should be applied so that the trees 

 may get the benefit of them early in the season. If very soluble 

 they should be put on in March or April, but stable manure or ground 

 bone shou.d be put on in the fall. 



INJURY BY COLD.
