GRAHAM FLOUE. 



Eight samples were collected under observation, and from the man- 

 ner of their manufacture are designated "imitation Graham." The 

 results of their analyses will be found in Table 8 (p. 19). Eighteen 

 samples, grouped in Table 9 (p. 20), were obtained from the stock on 

 hand, and according to the description of the method by which they 

 were prepared by the miller they are classified as " imitation Gra- 

 hams." 



Eight samples of Graham flour were made by the use of small 

 experimental mills in the bureau. For this purpose three samples 

 of wheat were ground, namely, a soft winter wheat, a hard winter 

 wheat, and a durum wheat. Two of the samples of wheat were 

 divided into three portions, one portion being ground through the cor- 

 rugated rolls three times, the second portion through the corrugated 

 rolls five times, and the third portion ground on a burrstone mill. 

 The soft winter wheat was passed through the corrugated rolls only. 

 The analyses of these 8 samples are given in Table 1.
