the dealers. That it still is in other markets and is only kept 

 out because of the feed law, is illustrated by a sample (No. 9977 

 with 24.75 P er cen t of protein) that was offered a Maine dealer 

 and by him sent to the Station for analysis. 



Cottonseed feed meal has been found in other states, but none 

 has yet come to Maine. A sample was sent to the Oscar Hol- 

 way Company of Auburn, which they sent to the Station. It 

 analyzed as follows : 



Sample No. 10,077, 5-88 P er cent water; 4.38 per cent ash; 

 23.88 per cent protein; 21.57 per cent fiber; 6.82 per cent fat. 



When it is remembered that good cottonseed meal carries 

 about 7 per cent of crude fiber, the bad quality of this feed meal 

 is even more apparent than its low protein content indicates. 



LINSEED MEAL (ANALYSES PAGE 44). 



Linseed meal is made by grinding flax seed from which the oil 

 has been more or less completely removed. "Old process" meal 

 is made from oil cake from which as much as possible of the oil 

 has been removed by pressure. In the "new process" the oil is 

 extracted by the use of naphtha. Old process meal carries more 

 fat and less protein than new process. Because of the method 

 of manufacture, new process meal is somewhat more uniform in 

 composition. Cleveland flax meal is a trade name for a new 

 process linseed meal. Oil meal is quite a common trade name 

 for old process linseed meal. 



Most of the oil meal was up to its guarantee in protein. No 

 evidence of any adulteration of this class of feeds was found. 

 Quite a number of samples of American Linseed Oil Company's 

 meal were taken from lots that were apparently wrongly tagged. 

 They should have been labelled old process and guaranteed. 32, 

 instead of 37.5 per cent protein. Fat was determined in two of 

 these samples low in protein and they were found to carry much 

 more fat than new process meal would. The samples referred 

 to in the foot note on page 44 were doubtless all from old pro- 

 cess meal. Because of the relatively lower price, more linseed 

 meal has been used than for many years. 



GLUTEN MEALS AND EEEDS (ANALYSES PAGE 45). 



Gluten meals and gluten feeds are by-products left in the man- 

 ufacture of starch and glucose from Indian corn. Corn consists
