 Chas. D. Woods. 



In the season of 1903 five experiments upon the growing, 

 harvesting, and storage of potatoes were undertaken as fol-

Variety test for resistance to blight. 



The effect of Bug Death vs. Paris green on health of vines. 



The use of a ready prepared vs. quick lime for the preparation 

 of Bordeaux mixture. 



Early vs. late harvesting as affecting the amount of rot. 



Storage in large bins vs. small bins, barrels and crates as 

 affecting the development of rot in cellar. 



The results of the first four experiments are here reported. 

 The experiment on storage will be finished in April and reported 

 as soon thereafter as practicable.

 of each to be sprayed with Bordeaux mixture and part of each to

 Aroostook County, varieties were selected and planted as
