loams and clays; and indeed, on any good soil, which is rich in humus. It also grows 
on the better kinds of sands, or on calcareous soils, provided that there is a sufficiency 
of moisture; in such cases the yield is; however, much diminished. In general, it thrives 
better on moist, stiff soils; than on those of a dry and light type. It can be grown with 
profit on heavy cold clays.

Cocksfoot thrives on well-manured land, and, if appropriate mixtures are used, man- 
uring is richly repaid. It can with advantage be used on irrigated ocround ; then, the grass 
becomes tall and luxuriant, attaining a height of 5 ft. or more. 
Growth, Yield, Nutritive value. Cocksfoot vegetates Iuxuriantly; the grass which it 
produces forms simple, compact tufts which stand well out of the ground, forming cushions 
of grass; when sown by itself, therefore, it does not form a complete sward, and the whole 
erass is cushion-like and unequal. In the first year after sowing, the development 1s mo- 
derate, the produce consists mainly of leaves with a few culms; in the second year, a full 
yield is obtained. Growth commences early in spring, and by the end of May or the be- 
cinning of June, the grass is in flower. If possible it should be cut before flowering, 
because the culms then become hard, and are not so readily eaten. Since cocksfoot forms 
one of the main constituents of the hay grown in Switzerland, farmers there say that hay 
should be made when cocksfoot is coming into flower. Another Swiss proverb is, that 
»Cocksfoot grows under the scythe«, Its herbage, which springs up so quickly after cut- 
ting, is at first, of a pale green colour. This, and the rapidity of its growth, distinguish 
it at once from other grasses growing with it. After each mowing the number of culms which 
are produced diminishes, while the amount of leaf increases. The leaves form excellent 
fodder and may be used either green or dry. Of all grasses, this probably yields the most 
nutritive aftermath.
