116 FRUIT CULrVRE. 



is alone applied as a remedy for the " yellows," 

 Professor Goessman recommends three or four 

 pounds to a tree six or eight years old, spread 

 iipon a circle of eight feet radius, but not ap- 

 proaching within one foot of the trunk. A thin 

 mulch of litter spread over the ground would in- 

 sure a more uniform and a safer distribution of 

 the potash, which should be afterwards applied. 

 In this connection it should be stated that the 

 disease appears to be contagious, and that cases 

 are cited of inoculating young and vigorous 

 trees by contact with diseased trees. On the 

 other hand, repeated experiments in the free use 

 of potash have indicated that a vigor of consti- 

 tution may be given which enables the tree to 

 resist the attacks of parasitic fungi. Should 

 this prove to be true on general trial, it would 

 indeed give a new phase to peach culture, and 

 prove an inestimable boon to the country. 



The Peach or Plum Rot (^Mojnlia fructi- 

 ijena). — This is caused bj^ a fungus Avliich is 

 the cause of great loss to some varieties in 

 some seasons. See a full description of the 

 disease and the remedies, under the head of
