AGRICULTUKAl. AITIMUMIIATION BII.I,, IWI. 247 



There is niiotlier ehnnj^e in iliat item. Ai tlir prrM'rjt tiiiu" there is 

 pn>vi:ij{)ii for nine hihornlory liel])ers und for «»ne skilled luhorcr at 

 salaries of $S4() each. Wv have ask(>(l that these he ])la<(Ml under one 

 heading; and «;iven as 10 iahoratory helpers or lah«»rers, without any 

 ehan«;e in salary at all. Tlu' pui-]>ose of that is to make it im-vsihle 

 for us to jjet from the civil servue rejjister the type of man that mi^ht 

 he re<|uired for some work wiiich we have in the Iahorat«»ries. and we 

 can iret more ellicit'nl men and men to nu'et the needs of lahoratories 

 in certain sections more readily if we «lo not have the tw»» lists and 

 can ap])oint them either as Iahoratory heljx'is or lalmrers. 



Mr. Andkk.son. Are the places you have dro|)])ed m»w \ aeant '. 



Mr. Ca.mi'UKLI,. Sonu* of them are va<ant now and all of them will 

 he vacant we ct)ntemplate hy the time this hill »;oes into effect. 



IXVESTIC.ATION OK AIMM.lCATlON OF CHKMISTKY TO ACiRlC TLTURK. 



The next item is for a»;ricultural investijjations. This is the appro- 

 priation out of which the fundamental a}.jricultural clu'mical research 

 work is supported. We have various lines «»f chemical activity in the 

 lield of aj^riculture paid from this fund. All of these projects of work 

 are formulate<l and promoted, of coui-se, with an vyv to the under- 

 lying:; economic significance of them. I may say to you. and perhaps 

 this would he the pertinent place to hring it in. that the work of the 

 Bureau of Chemistry divides itself naturallv int<^ two primarv suh- 

 divisions. The first is the research work or investigational worl\. and 

 the second is the regulator}- work, such as the enforcement of the 

 food and drug act, as well as tea importation act. Now . the research 

 work is of two types. First, that work which has to do with primary 

 research in the field of agriculture looking toward cultural phases, and 

 second, that work which has to do with the emph)yment of chemistry 

 in the solution of those prohlems which exist in manufacturing estah- 

 lishments utilizing agricultural raw materials. In other words, it is 

 technological rather than cultural, but both of which have economic 

 importance. 



Some of the work in the technological field is supported hy 

 specific or particular appropriations. Those we will come to later. 

 Hut all of tne fundamental research work of a cultural kind, in which 

 chemistry is employed in the whole agricultural scheme, is supported 

 from this particular appropriation. 



Those which have economic significince, illustrated in the most 

 direct way, of course, are such undertakings as the utilization of 

 agricultural waste materials for some beneficial purpose. That can 

 be illustrated by the work which has been done in a stuily of classes 

 of waste materials and their suitability and value for use as stock 

 feeds. One of the laboratories in the bureau has been working on 

 this thing for some few years, and bulletins have been published on 

 the basis of materials which lend themselves to tiiat use. Of course, 

 you are familiar with the work we have done, more particularly in 

 California, in the citrus fields and the utilization of cull oran<jes, 

 products which formerly found themselves valueless and which, when 

 they had a sale, would bring nothing more than approximately S'2 a 

 ton hut which are now being sold regularly and contracte<l for (m the 

 basis of somethinjr like $30 a ton.
