AUXILIARY WORK. 127 



Of the reports wliii-h hiivr ln'cn it'coivod ol" work (.•onducted by tlio 

 growers, it i.s thou^fht best to include a few from those reoions where 

 curl is most couunon. The reports given are of nmch value, and in 

 numerous cases the}'' show that the experiments were carefully carried 

 out. Representative reports will be given from the lake shore fruit 

 belt of jSIichigan, from the Willamette Valley, Oregon, where peach 

 culture has been greatly checked by curl, and from several growers in 

 California and (dscwhere. An effort has been made to present these 

 reports, which iia\'e been carefully tabulated, in as compact form as 

 possible. 



NOTES ON THE AUXILIARY EXPERIMENTS IN- MICHIGAN. 



A very considerable luunbcr of peach growers in the more northern 

 portion of the Michigan fruit belt received from the Department a 

 request to undertake spraying experiments in the winter of 1893-94 

 for the prevention of peach leaf curl. Among these orchardists was 

 Mr. Smith Hawlev, of Ludington. This gentleman, as well as several 

 other growers of Mason and Oceana counties, entered heartily into 

 the work, the result being that at present a very large number of 

 orchardists are annually spraying for curl in that region. The work 

 conducted ))y Mr. Hawlev involved the testing of a number of sprays 

 in early and late winter with one and two applications. It was very 

 carefull}' carried out, and as the disease developed quite seriously in 

 that region in the spring of 1894 his results are most interesting and 

 valuable. The data supplied by his report are presented in the fol- 

 lowing table and notes:
