EXPERIMENT STATION RECORD. 



Vol. XV. July, luo-t. No. 11. 



This namlxn- concludes the liftconth vohinic of the Record, except 

 the index. The index niimlxM- will, as usual, constitute No. 12, and 

 the work on this has heen kept so well up with the current numbers 

 that it will be issued quite promptly. Special effort has been made 

 in this direction for several years past, for it is recognized that the 

 permanent value of the Record depends laro-ely on its indexes, and 

 that it is a great advantage to those wdio iile it permanently to have 

 the index in their hands as soon as possible after the conclusion of a 

 volume. 



The general index, which has been so long promised, has at length 

 been issued. This has been in press since last September, and has suf- 

 fered several unavoida])le delays due to the shortage of some of the 

 type used, as well as the usual delays incident to reading the proof. 

 The manuscript was so pondei'ous that it was necessary to leave many 

 matters to be attended to in the proof. This hnal work was made 

 more dithcult by the inal)ility to have the whole index in type at one 

 time. This w\as impracticable from a t3'pographical standpoint. The 

 plates were stereotyped as fast as the proof was read, so that the final 

 changes necessitated cutting the plates or resetting, and hence had to 

 1)6 limited to those absolutely necessary' to accuracy. 



A large amount of time was expended in the effort to group entries, 

 so that a subject would be found complete by persons approaching it 

 from somewhat different points of view. There are always two and 

 frequently more entries for each item, and cross references are used 

 where \'er it was thought the}^ would be an aid. The result is a volume 

 of six hundred and seventy-one pages, which furnishes a complete 

 index to the work of the experiment stations and of this Department 

 since the Hatch Act went into effect, and since about 1898 to the more 

 important investigations of a similar character in foreign countries. 



The range of sul^jects revealed l)y casually ruiming over the index 

 is hardly less surprising than the number of entries included under 

 some of the larger subjects. The longest of these. Milk (and Milk 

 production), occupies nearly eleven double-column pages; Soils, nine 

 and a half pages; Corn, eight; Wheat, seven; Cows, six; and Butter
