toes with a light yield and an earh' rust. The yield in 1896 was about 

 100 barrels per acre and in 1897 about 50 barrels. The soil is light 

 red loam and, like most land in that vicinity, is on a shell-like lime 

 rock ledge. The field was plowed in the fall of 1897, and harrowed three 

 times in the spring with a spring toothed harrow. It was planted with 

 a planter and hoed with a horse hoe. The field had received no manure 

 until in 1896 and that year, and in 1897 and in 1898 it received about 

 500 pounds of complete fertilizer per acre. In 1898, the crop was 

 planted May 19 and harvested between September i and 20. 



The crop was sprayed twice with Bordeaux mixture, July 30 and 

 August 9, but it was too late to save the plants from the blight. The 

 yield was about fifty barrels of merchantable potatoes and fifteen bar- 

 rels of small ones, per acre. 



A'o. 3037, Beauty of Hebron. These potatoes were taken from a 

 field adjoining that from which No. 3036 were taken. The field was 

 plowed for the first time in the fall of 1897 and the crop was grown on 

 the sod without the addition of any fertilizing materials. 



Nos. 3038 and 3039, White Elephant and 3040 and 3041, Delazvare. 

 These samples were from T. B. Bradford, Golden Ridge, Sherman, 

 Maine. The land had a slope to the north; had been in grass until 

 October, 1897, when it was plowed. The soil was dark soil, inclined to 

 be wet, and was not underdrained. The sub-soil was gravelly. It 

 received about ten two-horse loads of barn manure, broadcast, over the 

 field and about 500 pounds of fertilizer per acre; the fertilizer was 

 applied in the drill. The field was planted June i and hars'ested 

 September 28. The whole field was spraj^ed three times with Bor- 

 deaux mixture by the use of an Aspinwall Spraj-er; in addition to this, 

 sample No. 3038 was sprayed more with a knapsack sprayer. At the time 

 that had been sprayed five times, the others were killed by rust. There 

 were forty-five barrels of merchantable potatoes and seventj^-five bar- 

 rels of small potatoes per acre. All of the potatoes rotted very badly, 

 and the decay began before any of the leaves were killed. 



Nos. 3044 and 3045, White Elephant. These samples were received 

 without the name of the sender. Three thousand fortj'^-four was 

 not sprayed and 3045 was sprayed with Bordeaux mixture. 



Nos. 3046 and 3047, White Elephant. These were grown by R. S. 

 Hoyt of Fort Fairfield. The field has a slope to the northeast and was 

 in pasture previous to 1896. In 1897, a crop of potatoes was grown with 

 the addition of 300 pounds of fertilizer. The yield was about sixty 

 barrels. The field was plowed again in October, 1897, harrowed ^lay 

 20, 1898, planted May 24 and har\-ested September 21. Four hundred 

 pounds of complete fertilizer were used, applied in the drill. The part 

 from which No. 3046 was taken, was sprayed twice, and 3047 was not 

 sprayed. The j'ield was sixty-five barrels of merchantable potatoes and 

 twenty-five barrels of small potatoes per acre. 



Nos. 3050 and 3051, White Elephant. Grown by Powers Bros, of 

 Caribou. The field bore potatoes in 1895 ; was seeded to oats in 1896 

 and grew a crop of red clover in 1897. The soil is a medium light clay 

 loam with a gravelly sub-soil. The field was plowed in October, 1897,
