the opposite course may be advisable. Sucb being the 

 case, eacli farmer must strike the balance for hiuiself 

 between quality, quantity, and cost. 



Rowen. — It is evident that the vahie of rowen must be 

 very variable, according to the soil, the time at which the 

 first ci'op was taken off, etc. It is generally likely to be 

 cut at a comparatively early period of growth, and then, 

 if properly cured, constitutes an excellent fodder. It is, 

 however, more liable to injury from wet than the coarser 

 hay of the first crop, and may easily suffer considerable 

 damage in this way. 



Pasture G-rass. — The high nutritive value of the young 

 grass of good pastures is evident from the foregoing para- 

 graphs (compare the analysis on p. 292). The question of 

 the relative advantages of pasturage or stall-feeding, how- 

 ever, is a purely economical one, and as such is entirely 

 outside the scope of this work. 



Proportion of Non-Protein in Hay. — Recent inves- 

 tigations, especially those of Kellner, already alluded to (p. 

 37), have shown that a comparatively large proportion of 

 the nitrogenous matters of hay and other coarse fodders 

 is not albuminoids, but belongs to some of the classes of 

 non-albuminoid nitrogenous matters enumerated on page 

 34, and which we have collectively designated as non-pro- 

 tein. In thirty-one samples of various kinds of coarse 

 fodder, he found {loo, gH.^ p. 2i5) the non-albuminoid ni- 

 trogen to range from 0.102 to 2.133 per cent, of the dry 

 matter of the fodder, and from 7.5 to 38.5 per cent, of the 

 total nitrogen. In meadow hay the range was 0.102 to 

 0.983 per cent, of the dry substance, and 7.5 to 348 per 

 cent, of the total nitrogen. In nineteen samples of hay 

 examined by the author,'^' the non-albuminoid nitrogen was
