the Foundling hop resembles the Colgate variety, though LI Is clearly quite dis- 

 tinct. The Foundling seems worthy of trial by the commercial hop grower on

 nettlehead disease, (d) lateness of season (coming after the Fuggles)." [Jour-

"The Department of Agriculture is carrying on certain breeding experiments 

 with potatoes, and these resistant wild strains may prove useful for this pur- 

 pose. The tubers were gathered on very heavy clay soil from a piece of hind 

 which is completely water-soaked during at least three months in the year 

 and extremely dry for about seven or eight months in succession. The tubers 

 possess, therefore, certain resistant properties which it may be found useful to 

 impart to the cultivated varieties in the United States." (Schultz.)
