It is recognized that the value of these lauds must be proved before 

 capital will become interested in the reclamation of our large muck 

 areas. Considerable attention has been given to the accumulation of 

 data of value to development projects — the special type of drainage ma- 

 chinery, and the methods of clearing and breaking up these soils eco- 

 nomicall3^ It is assumed that every possible encouragement should 

 be given to men interested in the development of this tremendous re- 

 source which is now practically unused. 



It is evident that there should be a source of information and advice 

 on the various types of muck in Michigan to protect buyers who desire 

 unbiased advice and to encourage prospective development. This oftice 

 has functioned in this capacity by collecting information and giving 

 advice on reclamation jirojects. 



Data has been accumulated for the immediate publication of a bulletin 

 on the handling of muck soils and muck crops.

REPORT OF EXTENSION WORK IN ENTOMOLOGY. 



The work of the extension sijecialist in Entomology has consisted al- 

 most exclusively of giving advice and aid in control of insect enemies of 

 agriculture. Much of this has been in response to requests and the re- 

 mainder has been in cooi)eration with county igents in the various 

 parts of the State. Much of the time the eti'ort has taken the form of 

 making addresses at granges, extension schools, and meetings of farmers, 

 wherever the demand or the outlook made it seem i)rotitable. 



During the last half of the summer of 11)10 much attention was paid to 

 a search for European corn-borer. Ditferent districts which might have 

 been accidentally infested in tlu^ past and overlooked, were visited, in an 

 effort to locate areas of infestation, should any exist. Following this, 

 in view of the fact that the Hessian-fly is on the increase in Michigan, 

 efforts w^ere made to induce farmers to sow their wheat on a fly-free date, 

 especially in the southern ])art of the State. At the same time the search 

 for the corn-borer was kept up. 



Immediately after fhe winter set in, efforts were made by personal 

 visits to influence fhe Supervisors in the northern counties, through the 

 county agents, to pre))are for the coming grassho])i((M' camjiaign in 1920, 

 by supplying themselves with ])oison at a time when the pi-ice was down; 

 and in due course much efl'ort was expended during the spring and early
