judgment as to the value of the variety from the apparent crop 

 yield, size, smoothness, general appearance and cooking qualities 

 of the tuber. 



The seed was planted ]\Iay 18 and 19 on Air. John Watson's 

 farm, Houlton. Before planting all the seed was treated with 

 formaldehyde gas for scab fungus. The seed of each variety 

 was divided into two equal portions, and one portion of each 

 kind was planted on a field which was not to be sprayed, and the 

 other portion on a field which was to be sprayed with bordeaux 

 mixture in the usual manner. 



In the season of 1908, there was no late blight in the County 

 but early blight was quite prevalent in some places and mani- 

 fested itself on some of these potatoes. The crop was harvested 

 September 24 and 25, 1908. 



As a result of the test, 14 of the varieties have been discarded 

 as unsuiterl to Maine. Seed has been saved of the following 

 numbers,— 506, 511, 512, 517, 540, 542, 594, 596, 602, 610, 736, 

 4229, 4517 and Lowell's Green Mountain. It is proposed to 

 plant these both for blight resistance and for yield tests on the 

 John \^'atson farm in the season of 1909. Each variety will be 

 divided as in 1908 into two portions and part w'ill be planted on 

 a field that is to be sprayed and part in a field that is to be left 

 unsprayed. 



In the table which follows, there are given the notes and 

 observations made during the season of 1908. The observations 

 upon growth and upon the quality of tubers are made entirely 

 upon the crop from the unsprayed field. 



V.\RIETIES TESTED. 



501 Sophie. Seed small white potatoes which being planted on the 

 outside row did not have quite so good a chance as the others. Vines 

 strong growing and showed very little injury and practically no early 

 blight until frost. The yield was rather poor of small potatoes. 



Cooking test: Boiled, quite dry and mealy. Baked, rather wet. 

 Flavor, good. 



505 Irene. Seed received, 60 pounds small red potatoes. Vines were 

 vigorous and showed very little injury from early blight. Yield small 

 and rather inferior potatoes. 



Cooking test: Boiled, quite dry and mealy. Baked, quite dry and 

 mealy. Flavor, very good.
