ANNUAL REPORT TO HORTICULTURAL SOCIETY FROM 
CENTRAL EXPERIMENT STATION, ST. ANTHONY 
PARK, MINNESOTA. 
Members of the Minnesota Horticultural Society: 
LADIES AND GENTLEMEN: I have the honor to present herewith my 
fourth annual report of the work of the Horticultural Department of the 
Experiment Station of the University of Minnesota. It being an outline 
of the work done during the year ending Dec. 31st, 1891. 
Respectfully submitted, SAMUEL B. GREEN, 
Prof. Horticulture, University of Minnesota. 
St. Anthony Park, Jan. 18, 1892. 
APPLES AND LARGE FRUITS. 
THE RUSSIAN ORCHARD. 
This orchard is doing well. It has been planted six years and now con” 
tains about 1,300 trees, representing 240 varieties. A few kinds have been 
seriously injured by blight the past summer and such varieties will be dis- 
carded as unworthy of further trial. The varieties that blight the worst 
are the Aports, generally speaking, Red Streaked, Switzer, Antonovka and 
Anisomooka. (?) This orchard is of much interest to horticulturists visit- 
ing the station. I have purposely witheld from publishing much about it 
as conclusions drawn from the behavior of apple trees that have not borne 
several crops of fruit are of little practical value. But as a whole the 
trees are thrifty and hardy, and as promising as one could wish. The 
land between the trees has been planted to Hubbard squash for three 
years. This crop pays us well. It affords a most excellent shade to the 
ground during the hot weather and is out of the way early in the fall, 
leaving the soil exposed to the sun and thus allowing the early ripening 
of the wood. The trees are protected from sun-scald by a slight shade of 
corn stalks tied on the south side, and are banked up each autumn with 
earth. ‘ 
NEW ORCHARD. 
During the fall of last year about one acre of woodland on the north 
slope of the hill at the station was grubbed out, and last spring it was 
successfully planted to a variety of fruit trees as follows: 16 varieties of 
Russian cherries, 2 varieties of peaches, 4 varieties of plums, 1 variety 
apricots and 189 varieties of apples; in all, 360 trees. The advantages of 
this orchard lie in the northern slope and the altitude. It supplies us with 
what has been long needed by furnishing us with a favorable trial ground 
for varieties that only do their best on elevated land. 
SEEDLING APPLES. 
Probably no more important work can be undertaken by my department 
than to experiment in raising seedling apples. With this in view I have 
obtained seed from various growersin the state of about fifty different
