ARBORETUM. 



Some little attention has been given this valuable feature the past year 

 and there seems to be a feeling to regard it with increasing favor by our 

 horticulturists generally. ^ 



I can hardly urge this matter too strongly upon your attention. The 

 benefit to be derived from it must be far reaching in its consequences. 

 Additions have been made to it of over 100 species and varieties the past 

 year. 



To Harvard College through its Arnold arboretum we are indebted for 

 a fine collection from the generas Pyrus and Prunus and some others. 



RUSSIAN WILLOWS AND POPLARS. 



Many of these are growing in favor with our planters, and the general 

 opinion is that they have come stay and to form a valuable acquisition to 

 our list of trees. 



A new feature which we have discovered the past year is that the beau- 

 tiful trailing willow called Napoleon's willow, can be easily grafted on 

 Salix acutifolio. Treated in this way it will give a very desirable novelty 

 in ornamental trees for the lawn and something that our nurserymen 

 and amateurs will be pleased with. 



MINOR EXPERIMENTS. 



Many experiments have been undertaken, an enumeration of the details 

 of which would require much space, and so would be out of place in a 

 report of this nature. They were as follows : 



Experiments in the use of Bordeaux mixture on potatoes to check 

 blight. 



Experiments in the application of Minnesota tankage as a garden and 

 greenhouse fertilizer. 



Experiments in summer propagation of plants. 



Experiments with old and new squash. 



The results of these experiments will be furnished more in detail in 

 bulletins from time to time. 



Besides caring for the experiment work at the station, I have had 

 charge of the laying out and grading of the ground about the School 

 buildings, which has taken much care and attention. 



In closing I wish to again thank the members of the society for cordial 

 co-operation and the kindly interest manifested in the work of my de- 

 partment. 



REPORT OF EXPERIMENT STATION. 



BY CHAS. LEUDLOFF, CARVER, MINN. 



For this time my report is short r as Mr. Frost on the night of May 17th 

 shortened it very much, as my Russian apples, plum and cherries were 

 then in bloom nicely, but all blossoms were killed by that frost; the 

 Russian apples in my experimental nursery did well last summer; they 

 were all free from blight and made a good growth. In my orchard some 

 kind of crabs blighted very much and a few died down to the grouud. My 

 grapes also were damaged by frost and only a few baskets full of bunches 

 was the crop; strawberries only are picking; some of my plums (best 

 native) brought a good crop. The currants and gooseberries gave me a
