is showing some excellent resnlts in ilie difference in color and storage 

 quality of the two distinct types of Baldwin apples that have been dis- 

 covered in this orchard. 



Additional data has been obtained the past year on the storage of fruits 

 by freezing, a detailed account of which we hope to publish in the near 

 future. 



The lack of regular production of many of the orchards of Michigan 

 is due to a starved or half-starved condition of the trees. To meet the 

 immediate demand for information on fertilizing orchards and to stim- 

 ulate better cultural practices to insure a bountiful supply of moisture 

 and plant food to producing trees, a circular of general information on 

 this subject was recently published (Circular 43). 



Orchard fertilizer demonstrational tests were also started in many lo- 

 calities of the fruit sections through the cooperative efforts of our ex- 

 perimental and extension forces. In the Thomas Quinlan orchard of 

 Grand Eapids an investigation has been started of the nitrogenous re- 

 quirements of a typically starved orchard. This project is in cooperation 

 with the Soils and Botanical departments. 



At the South Haven Experiment Station the work the past season has 

 consisted largely of caring for the numerous young trees recently plant- 

 ed, and of the many seedling crosses that were made in the experiments 

 to obtain a desirable blight-resistant pear and a hardier peach, the two 

 principal lines of work being developed there at present. The property 

 has been maintained in a very tidy and respectable manner and some 

 landscape gardening improvements made during the past year. 



There is nothing of special importance to report upon at this time 

 regarding the other projects of the department. 



Respectfully submitted,

REPORT OF GRAHAM HORTICULTURAL EXPERIMENT STATION 



Director R. S. Shaw. 



Dear Sir: The w'ork the past year at the Graham Horticultural Ex- 

 periment Farm has consisted largely of removing old, dead peach or- 

 chards and fences, and of such other work incidental to the subduing of 

 a general farm to a systematic plan for a public experimental station. 



All of the available land for orchard planting, except a small area be- 

 ing reserved for a peach orchard, was set with young trees this spring in- 

 cluding a block of Montmorency cherries, a block of a few varieties of 

 sweet cherries, a block of Northern Spy apples, of Lombard plums, 

 and of Bartlett pears for experimental projects. 



Experiments were started to demonstrate the value of cover-crops and 

 ascertain the best cover-crop to be used as measured by tree-growth and 

 fruit-production. 



A soil cultural experiment was started to compare the relative cost of
