equal plots on a level piece of ground. They are kept care- 
fully separated in harvesting and threshing and the vields 
weighed and compared. One season is not enough, for dif- 
ferent soils and different seasons affect varieties unequally. 
But if the same kinds are tested for five years, the average 
result should be trustworthy. Table XCVIII shows the re-

sults obtained from the seven kinds which have been sown 
every year since 1896. These are the survivors of twenty- 
one varieties with which the experiment was begun. From 
these, in 1899, the Improved Ligowo was selected for seed, 
as showing the heaviest yield and best quality. Since 1900 
the field oats raised on the farm have been entirely of this 
variety, and 300 to 400 bushels of seed has been sold each 
year. The oat is becoming widely distributed throughout 
the region and reports received seem to indicate that it is an 
improvement in many cases over those previously grown. 
But, as the work of the station is continuous, efforts were 
at once made to secure a number of new kinds for further 
trial, in the hopes of finding something still better. Seed 
was received by the aid of the U.S. Dept. of Agriculture, 
from Sweden, Russia, Germany, Finland and Belgium, and 
some Canadian oats were added, which had stood well 
in the tests at the Government Experiment Farms. In all, 
twenty were secured, which with the nine best of the old 
kinds, are shown in Table XCIX. 
NoTEe.—The yield for 1900 was thrown out as it was impossible to save all the 
grain in harvesting, on account of continued wet weather.
