From the data at hand the authors have I'ecalculated the relative values of 

 timothy hay, clover hay, meadow liay, and maize meal, using timothy hay as 

 a standard. The results follow : 



Relative values. 



The clover hay used in the experiments reported was analyzed. 



Notes on the digestibility of pentosans, M. S. McDowell (Peiuisijlraiiid 

 Sta. Rjtt. 1906, pp. 9.'i-98). — In connection with steer feeding experiments made 

 with the respiration calorimeter and reported in part (E, S. R., 17, p. 571)) the 

 digestibility of pentosans in rations of clover hay and corn meal, of clover hay 

 alone, and of timothy hay and bran was studied. The average digestibility of 

 pentosans of clover hay alone was 60.75 per cent, of timothy hay alone 57.18 

 per cent, of corn meal fed with clover hay 94.73 per cent, and of bran fed with 

 timothy hay 66.39 per cent. 



" The effect of the corn meal has apparently been to increase the digesti- 

 bility of the hay. The corn meal, containing a comparatively small amount of 

 pentosan, when fed in small quantities especially emphasizes this fact. . . . 



" While the pentosans are apparently as digestible as the other plant sub- 

 stances, it must be born in mind that apparent digestibility does not neces- 

 sarily mean food value." 



Commercial feeding stuffs, 1907, E. H. Jenkins and J. P. Street (Connecti- 

 cut State Sta. Rpt. 1907-8, pt. 3, pp. 165-209). — Under the provisions of the State 

 law, 197 samples of feeds were collected and examined chemically and micro- 

 scopically. Forty samples sent to the station by individuals were also analyzed. 

 The materials examined included cotton-seed meal, old and new process linseed 

 meal, wheat bran, middlings, and mixed feed, maize meal, gluten feed, hominy 

 feed, rye bran, middlings, and feed, buckwheat middlings, ground rice, rice 

 bran, beet pulp, ground peas and beans, malt sprouts, dried distillers' grains, 

 dried brewers' grains, conmiercial mixed feeds, flax feed, proprietary dairy 

 and stoclj feeds, proprietary poultry feeds, meat scrap, and peanut refuse. 



Some of the samples examined were not guaranteed as required by law. In 

 most cases the goods seem to have met the guaranty, though this was not the 

 case with respect to 4 out of 11 samples of cotton-seed meal and 5 out of 9 

 brands of gluten feed. 



The digestibility of feeding stuffs, the purchase of commercial feeding stuffs, 

 and related questions are discussed. 



Commercial feeding stuffs, .J. E. Halligan (Louisiana f>tas. Bui. 98, pp. 

 I'll). — During the past season the station has analyzed 6,469 samples of com- 

 mei'Cial feeding stuffs under the State feed stuff law comprising cotton-seed 

 meal, rice bran, rice polish, wheat products, molasses feeds, corn chops, corn 

 and oat feeds, hominy, feed meal, brewers' grains, poultry feeds, alfalfa meal, 

 corn bran, and commercial mixed feeds. 



According to the classification adopted, 490 samples of the cotton-seed meal 

 examined were choice, 185 prime, 39 good, and 35 inferior.
