the station grounds belongs to the latter class, being 2i/2 to 4 feet deep 

 :iud resting upon a ledge of ealciferous rock the thickness of which is 

 J (10 feet or more. The portion used is fairly well drained by means 

 of tiling. The planting was done May 25, and, owing to a delay in 

 receiving the seed, the California Russet was planted June 0. Earlier 

 I»]an(ing will probably give better results with this variety than those 

 obtained during the tirst test, the potatoes otherwise having an at- 

 tractive appearance, being oblong and roundish with few and very shal- 

 low eyes and skin prominently russette^. 



The following table gives the yield of the six varieties which were 

 tested.

CONTINUATION OF POTATO EXPERIMENTS. 



A smaller ])]ot, or l-iS of an acre was used for the experiments 

 which have heen carried on since 1902. The fall planting was done 

 November t) and 10 and the spring planting was again done extra early, 

 or May 1.') and IB. Three rows each of Delaware and Rose of Erin, and 

 four rows each of Carman No. 3 and Sir Walter Raleigh were planted, 

 the rows being 'Sy-> feet apart and 4 rods long, thus making each sub- 

 division of three rows, as shown in the table of yields, equal to 1-250 

 acre, while the four rows subdivisions represent 1-192 acre. As here- 

 after shown, the sprouting and blossoming of the fall planted potatoes 

 were again earlier by several days and the ripening was 10 to 12 days 

 earlier. Adjoining the plot on the west side was (he barley plot men- 

 tioned as having been partially destroyed by cutworms, and it was 

 not until after .all the spring planted i)otatoes were up that it was 

 fully ascertained that the insects had also been working on the fall 

 jdanted ])otatoes and destroyed the sprouts before they appeared above 

 ground. The four rows of Sir Walter Raleigh nearest the barley plot 

 were entirely destroyed at the south end, Avhich includes the subdivi- 

 sion subse((u<Mitly liilhMl up and si)rayed. Adjoining (his variety was 

 the Jiose of Erin, and for (his reason (he hilled up ami sprayed sub- 

 division of this variety was damaged most. More or less of tlie south 

 end of the rows of the other two varieties was likewise destroyed, and 

 that the insects quit working before* (hey reached much farther east is 

 shown by the yields of Sir Walter Jialeigh and Rose of Erin on the 

 east side of the plot Avhicli includes the subdivisions cultivated level 

 and sprayed. The unsprouted seed potatoes, as found on June 20, were 

 still sound, and as a few had one or more unsprouted eyes left, there
