FOREWORD. 



A great deal has been accomplished and many changes have taken place 

 at the Upper Pemnsula Experiment Station at Chatham, since the publica- 

 tion of the last special report in 1918, as Special Bulletin Xo. 90. The present 

 report, Special Bulletin No. 110 is an attempt to present to the people of the 

 Upper Peninsula the improvements made and also a summary of the work 

 conducted and the results obtained by the Experiment Station workers at 

 Chatham for the past two j'ears. 



Formerly all of the work at the Station including land clearing, crop and 

 livestock production, has been handled by the Superintendent. During 

 the past two years, however, the ]Michigan Experiment Station has been 

 in a position to place two additional speciahsts at the Upper Peninsula Sta- 

 tion to be of ser^^ce to the farmers in that portion of the Stat-e. 



D. L. ^Mc^Millan, Superintendent, has general supervision over all of the 

 Station work and specializes in the hvestock production, a report of which 

 is given under "Animal Husbandry." J. E. Kotila has charge of work con- 

 nected with diseases and insect control on potatoes. The section of this 

 bulletin entitled "Potato Disease Investigations" is a report of his work 

 at the Station. G. W. Putnam, the plant breeder, has charge of all farm 

 crops experimental work and the report of his work is given in the section 

 entitled "Farm Crops". Mr. Putnam was largely instrumental in the as- 

 sembling and editing of this bulletin. 



All farmers and others interested in the agriculture of the Upper Penin- 

 sula should profit by this report and feel that the Station belongs to them 

 and that the work conducted there is for their benefit. We ask the cooper- 

 ation of all those interested in the development of northern ^lichigan.
