Special Bulletin No. 26, by L. R. Taft, Horticulturist 



The list of persons resident in Michigan, to whom the regular bulletins of the 

 Experiment Station are sent, now includes considerably more than thirty thousand 

 names, compelling the printing of an edition of forty thousand copies of each issue 

 to provide for the necessary reserve. The expense of printing so large a number 

 is a burden. Michigan agriculture is greatly diversified and specialized. This 

 means that bulletins of great value to a given section of the State or to farmers 

 engaged in a given industry would never be read by other farmers not specially 

 interested in the given line of work. It would be manifestly not economical to 

 print bulletins of limited interest for distribution to the whole mailing list. The 

 plan has therefore been adopted of printing a series of special bulletins limiting 

 the number of each edition to a quantity suflSclent to meet the probable demand. 

 Most of the earlier numbers of this list are now out of print. A full list of these 

 special bulletins follows:
