FOR W(H)I.-srOUKlNO WA.STK INVKSTKJATIONS. 



Keft'rrin«; to the item on paj^e ISS for the investijjation and develop- 

 ment of methcMls of utilizin<j wo(d-scourin<; waste: At the time this 

 was formulated, it did not appear that we W()uld he ahle to complete 

 that work hv the .'{Oth of .June, hut since the formulation of this 

 estimate we liave found that we could «;et the work through within 

 that time, and the de|)artment htus asked the permission of the 

 Bureau of the Hud^ret to withdraw this in its entirety. 



Mr. Andkuson. We will withdraw it for you. 



FOR THE STUDY AND IMPROVEMENT OF METHODS OF DKHYDRATING 



MATERIALS ISED FOR FOOD. 



Mr. C\\MPBELL. The next item, page 186, for the study and improve- 

 ment of methods of dehydrating materials used for food. That 

 work is continued in atti-mpting to determine the technological 

 prohlems involved more [)articularly with reference to the dehydra- 

 tion of vegetahles. The work very largely in the past has been done 

 in connection with fruits. The work nas heen concentrated in one 

 laboratory, and that laboratory is the citrus-prtxiucts laboratorv in 

 Los Angt'les. Calif. We have made arrangements that will make it 

 possible to obtain the fruit at little or no cost. The attempt was for 

 the purpose of stuilying the best methods for dehydration and to 

 get concerns that were interested in having products dried to pur- 

 chase those products, iurnish us raw material, and let us turn over 

 to them the finished article, so that we could make our study in that 

 fashion without the expense involved in the j)urchase of the material 

 ourselves and attempting U) market that afterwards, which ct)uld 

 not be done in a commercial way bv us, and our whole efforts have 

 been with the purpose in view of determining what the proper 

 technological method was. moie especially in regard to what is the 

 best method for the dehydration of vegetables. 



Mr. Anderson. Have you done anything in the way of develop- 

 ment for a market for these products ( 



Mr. Campbell. That thing has been urged by the industry itself, 

 Mr. Anderson, but 1 can not see that that is any part of our business; 

 and we ourselves have not attempted to do anvthing with that. Very 

 naturally it could not be (hme with a fund of tbis size, and our concern 

 is to make available through the investigatiitns that we have under- 

 way the methods which should be employed for the manufacture of a 

 standardized article and then (|uit with that.
