product a careful examination, and his report concerning it 

 includes the following statements: 



" ' These goods were sent to an expert on food mixtures and 

 adulterations, at the Connecticut experiment station, who 

 reports as follows: "I have examined Blatchfords calf meal 

 under the microscope, and find it contains linseed meal, some 

 product from the wheat kernel, some product from the bean 

 kernel and a little fenugreek. The linseed meal appears to be 

 the chief constituent. The wheat product is bran, middlings 

 or some similar product consisting of starchy matter mixed 

 with more or less of the seed coats. Bean bran was present in 

 considerable amount and more or less of the starchy matter. " 



" ' In a letter just at hand from Mr. J. Barwell, the proprie- 

 tor of these goods, he says: "Regarding the ingredients, I 

 cannot give you the exact constituents of it, but I may say that 

 it is composed mostly of locust bean meal with leguminous 

 seeds, such as lentils, etc., and oleaginous seeds, such as flax 

 seed, fenugreek and anise seed, all cleaned, hulled and ground 

 together and thoroughly well cooked. There is no cheap mill 

 food and no low grade feed enters into its composition. I am 

 prepared to go into any court in the United States and make 

 an affidavit that there is no farmer in the United States that 

 can compound Blatchford's calf meal for less than $3.50 per 

 hundred. ' ' 



"'Locust bean meal, which Mr. Barwell claims to be the 

 chief constituent of Blatchford's calf meal, is practically not 

 used in this country as a cattle feed. The average of ten 

 English and German analyses show it to carry: Water, 14.96 

 per cent; ash, 2 53 per cent; protein, 5.86 percent; crude fiber, 

 6.39 per cent; nitrogen free extract, 68.98 per cent; fat, 1.28 

 per cent. 



" ' It is evident, from the chemical analyses, that locust bean 

 meal cannot be the chief constituent of Blatchford's calf meal, 

 but that the microscopist is correct that liaseed meal is the 

 chief constituent. Locust bean meal has only 6 per cent of 

 protein, and, in order to make a mixture carrying from 26 to 

 33 per cent of protein, it would be necessary to add large quan- 

 tises of goods, like linseed meal, rich in protein. As seen 

 from the analyses, Blatchford's calf meal has a feeding value 

 somewhat inferior to old process linseed meal. Whatever it 

 may cost to manufacture, no man who has sufficient intelli-
