 FIELD PLOTS OF POTATOES. 



The following field plots of potatoes were included in the area devoted to experi- 

 mental purposes. The land on which these potatoes were planted was similar through- 

 out, and the preparation and treatment were the same for all. The soil was a sandy 

 loam, more or less mixed with clay. The previous crop was experimental plots of 

 wheat. After the wheat crop was cut the land was gang-ploughed shallow to start into 

 growth any shed grain or weed seeds lying on the surface; later in the autumn it was 

 again ploughed seven to eight inches deep. During the winter of 1900 and 1901 it 

 received a dressing of about 12 tons of fresh barn-yard manure per acre, which was 

 placed during the winter on the frozen ground in small piles of about a third of a cart- 

 load each to prevent fermentation. This was spread in the spring, ploughed under 

 about six inches deep, and harrowed with the smoothing harrow, then made into drills 

 two and a half feet apart and six inches deep for planting. The sets were put from 12 

 to 15 inches apart. They were all planted May 18, and dug October 4.

Plots 8, 9 and 10 were partly in low land, which accounts for the smaller yi

SELECT LIST OF VARIETIES OF POTATOES. 



In this list is given the average yield per acre obtained during the past three to 

 seven years from the 'most productive varieties grown at all the experimental farms, 

 with the length of time they have been under test. Only those are included which 

 bave been three years or longer under trial. On this account many of the newest sorts 

 do not appear in this list. During the past seven years a large number of varieties 

 have been tested, and quite a number of different sorts have failed to reach that stand- 

 ard of productiveness required if their cultivation is to be continued. The standard 

 for potatoes is fixed in the same way as that for oats. This will be found explained 

 under ' Select list of oats.' 



The following 29 varieties have thus been dropped from the list during the past 

 two years. Algoma No. 1, Columbus, Crown Jewel, Charles Downing, Early Gem, 

 Fillbasket, Freeman, Good News, Honeoye Kose, Hopeful, Harbinger, Ideal, Light- 

 ning Express, London, King of the Eoses, McKenzie, Monroe County, Orphans, Pride 

 of the Table, Peerless Junior, Queen of the Valley, Russell's Seedling, Record, Satis- 

 faction, Seedling No. 214, Stourbridge Glory, Table King, Victor Rose, World's Fair.
