found in all parts of the infested plant and also in the surrounding 

 soil," This fungus seems to be closely related to the one which causes 

 the black rot of the grape. Further investigations are needed, par- 

 ticularly in regard to the soil conditions favoring the growth of this 

 disease, and the means of destroying the fungus without injuring the 

 cranberry plants. For this work, which must largely be done on the 

 bog, the Station desires the cooperation of those cranberry growers 

 " who are willing to share in the labor and expense of a systematic 

 search for a remedy.''

Thk potato rot, B. D. Halsted. D. Sc. (pp. 2— t). — A brief, pop- 

 ular account of the fungus {Phyto/^hflioiv hifestans) , the conditions 

 favoring the rot, the treatment of infested fields, and preventive 

 measures. Among the i)ractical suggestions made are the following: 



The rot is favored by moist and hot weather and will affect potatoes 

 stored in damp, warm, and close cellars, as well as before digging. 

 A loose, light soil does not promote the decay like a clayey one. The 

 disease is undoubtedly often spread by the seed potatoes used. '' If 

 possible the potatoes for planting should be obtained from a locality 

 where the rot has not prevailed." As a rule, the potatoes should be 

 dug as soon as possible after the vines have been attacked by the rot. 

 The diseased vines should be raked into heaps and burned to destroy 

 the germs before the tubers are dug. Air-slaked lime, a handful or 

 so per bushel, may be dusted over the freshly harvested potatoes to 

 destroy any adhering germs.

Questions relating to general rAR:\i practice, E. B. Voorhees,

 do not consider their business profitable under present conditions, the 

 Station has pre2:)ared and sent out a list of questions to special and 

 general farmers throughout the State to find out — '"(1) Methods of 

 rotation. (2) The proportion of stock kept to acreage. (3) The 

 kind and quantity of food used per day. (4) The method of feeding 

 and practice as to shelter. Definite information of this character 

 will be of great importance, and will have an influence in determining
