If the measure for establishing experiment stations in the different SUiies, 

 that was advocated by this Society at its meeting here two years ago, should 

 become a law, then this subject could receive the attention due to its im- 

 poriance by em]>loying a tompelent person at each station to collect mate- 

 rial and make experiments under the direction of a central office, connected 

 with the Department of Agriculture if you please, that should be provided 

 with a comjilete library and all the apparatus necessary for the most 

 thorough investigation. 



Prof. Riley, the entomologist of the Department of Agriculture, has created 

 a very similar system for conducting his researches, having his assistiint.-^ lo- 

 cated in different parts of the country. 



Such an organization as is here briefly outlined once established, and we 

 could hope in time for results that would be of the greatest importance to 

 all the material interests of the country. 



DISCUSSION OX MR. EARI.k's PAPKII. 



Mr. WilllanhH, of Xew Jersey — Wliat effect hits tlie leaf rust on 

 the berries? 



F. S. Earh', of Illinois — Tiic rust on the plant scri(»u>ly affects 

 the berry ; the fruit on such plants being small a:ul seedy. 



Mr. McClave, of Michigan — Is the red rust on the raspl)eri'y ami 

 blackberry the same as that affecting the strawberry? 



P\ S. Earle — No; entirely ditferent. But few reports Ironi Mich- 

 igan mention the strawberry rust. The strawberry growers of 

 Southern Illinois seem to suffer most from the rust. 



3Ir. Cayicood, of New York — Is it more common in wet weather".' 



F. S. Earle — It is worse in dry weather. 



Mr. Kellogcj, of Wisconsin — Do you use one, two or live l)U>lnls 

 of lime to the acre? 



/■'. •^'. Earle — No; probably not over one half a bushel. 

 Ih\ IIujjc, of Georgia — Have you tried ashes? 

 Jfr. Earle — Yes; but can not say as to its efficiency. 

 I)r. Hapc — The Sliarj)lcss is one of the few varieties not at- 

 tacked by the rust with us. 



Mr. Pierce, of Ohio — 1 have known the black rust very abundant 

 on a li( Id where ashes had been liberally used as a manure. The 

 roots iiad decayed in spots, lilack rust probably begins under 

 ground.
