identification of inspectors, the abuse of the guaranty for advertising purposes, 

 tlie labeling of succotash, the use of guaranties and serial numbers thereof, and 

 the interstate transportation of imported meats and meat food products. 



According to the decision rendered as to succotash, this word, if used without 

 qualification, is understood to imply that the product designated is composed of 

 green sweet corn and green I)eans. If soaked beans or soaked corn are used 

 the fact must be declared in the proper manner.

Protein in vetch hay, A. L. Kmsely {Oregon Sta. Rpt. 1905, pp. 59-65). — 

 Continuing earlier work (E. S. R., 16, p. 801), the protein content of vetch was 

 studied, the work extending over .3 years. Samples were cut at the proper 

 stage for hay making, cured, and analyzed. The average results are summarized 

 in the table which follows:

These results show that there has been, thus far, a steady increase in the per- 

 centage of protein in the vetch hay. Two or 3 samples of this year's crop 

 ran extremely low in protein, while many samples contained over 20 and a few. 

 more than 2.5 per cent protein. All determinations were made either in duiili- 

 eate or triplicate, corrections being made accoi'ding to blank determinations. 



Early work of the station on the digestibility of vetch hay is cited (E. S. It.. 

 17, p. m). 



Relative values of feeding stuffs, H. P. Armsby {Pcnn-'iiitvania St<i. Bill. 11, 

 rer. cd., pp. 16). — The results reported for clover liay in tlie first edition of the 

 l)ulletin (E. S. R., 17. p. 380) were suspected of being too low. a suspicion 

 which later experiments confirmed. This i-evision contains the corrected 

 results. 



Prickly pear and other cacti as food for stock, II, D. Gkiffiths and R. F. 

 Hare (New Me.vico Sta. Bill. 60, pp. 135, pis. 7, figs. 2, folding tables 7). — This 

 bulletin reports 187 proximate analyses and 20 ash analyses of samples of 

 different sorts of cacti collected from central Texas to California and south- 

 ward to the central plateau of JNIexico. 



In general the analyses show that the cacti may be said to compare favorably 

 with ordinary green foddei's and root crops. The apparently liigh protein and 

 fat content in the fruit of some species is due, as the authors point out, to the 

 large proportion of these nutrients found in the seed. As the seeds are sur- 

 rounded by a dense layer of indigestible tissue, the high values for protein and 

 fat are misleading. '* Tlu= analyses sliow that the fodder value of the fruit (if 

 cholla (Opiintia fiilgida) ;ind related species investigated is little more tliTiii that 

 of the stems." 



" There are many points of si)ecial interest in connection with the ash analyses, 

 especially the high content of potash, magnesium, and calcium. Although the 

 cane cacti show a relatively higher food value, practical considerations relating
