Appropriate manuring is beneficial ; fresh manure is much less useful than that which 
is thoroughly decomposed. 
Growth, Yield, Nutritive value. As already explained Smooth-stalked meadow-grass pro- 
duces very long underground stolons which ultimately bend upwards and form tufts of 
branches in the air. 
In the second year, the stolons become very numerous; accordingly, the ground be- 
comes thickly and completely covered with grass. In the first year, the amount of herbage 
is small and no culms are produced; here and there, bare spots of ground occur, Full 
development is reached in the second and third year of growth, The shoots come up toler- 
ably early. The time of flowering varies with the situation, and extends from the end of 
May to the middle of June. In the second cutting, the produce consists entirely of long 
leaves (4—12 inches, accordingly to the quality of the soil); no culms are produced, not 
even such as lie upon the ground and strike root (as some authors erroneously state) ; 
these leaves grow very slowly, the aftermath is therefore small. Vianne obtained from a 
loose, light, fertile soil, per acre: —

This grass is best cut when in flower. When older, the culms are dry and hard, and 
the leaves, though still green, tough and leathery. 100 Ibs. of grass give, on an average, 
30 Ibs. of hay. 
According to Sprengel, the yield per acre may be assumed to be 3,500—4,400 Ibs. of hay ; Vianne 
obtained 6,250 lbs.; Sinclair 4,296 lbs. According to the Zurich analyses 100 Ibs, of hay contain
