The Digestibility of Cattle Foods. 

 The digestion experiments herein reported were made 

 during the autumn, winter and early spring of 1904—05 and 

 1905-06, and are kno^vn as Series X and XI. The usual 

 method was employed, an illustrated description of which 

 is to be found in the eleventh report of the Massachusetts 

 Experiment Station. The full data are here presented, with 

 the exception of the daily production of manure and the 

 daily water consumption, in which cases, to economize space, 

 averages only are given. The periods extended over four- 

 teen days, the first seven of which were preliminary, col- 

 lection of fseces being made during the last seven. Ten 

 grams of salt were given each sheep daily, with water ad 

 libitum. Three lots of Southdown wethers were employed 

 in the several trials, and were known as the Old Sheep, 

 Young Sheep, and Paige Sheep. The former were fully 

 six years of age, and the latter two lots three to four years. 



Series X. 

 The results obtained in this series on the whole can be 

 pronounced satisfactory. In periods I., II., III. and IV. 

 the same hay was used as in the year preceding, and the 

 digestion coefficients employed in calculating the results of 

 these several periods were as follows : ^ —
