4. _Tall Oat-Grass._--A valuable grass, deserving increased attention. It will produce three crops in a season; grows four or five feet high, and should be cut for hay when in blossom. Of all grasses, it is the earliest and best for green fodder. 5. _Tall Fescue._--Cut in blossom, it contains more nutriment than any other known grass. Grows well by the sides of ditches, and is well adapted to wet bogs, as, by its rapid growth, it keeps down coarse, noxious grass and weeds. 6. _Rye Grass._--This is extensively cultivated in Scotland and in the north of England. It is mixed with clover. Respecting its comparative value there is a diversity of opinion. Some do not speak well of it. 7. _Red Clover and White Clover._--See article "Clover." 8. _Lucern._--This yields much more green feed at a single crop than any other grass. For soiling cattle it is one of the best, and may be cut twice as often as red clover. This makes a good crop, soon after time for planting corn. Common corn or pop-corn, and later, Stowell's evergreen sweet corn, are the best for soiling cattle; but for early soiling, use lucern, or some other quick-growing, large grass. Lucern needs clean land, or cultivation at first, as young plants are tender. The tap-root runs down very deep; hence, hard clay or wet soils are not favorable. It stands the cold, in latitudes forty to forty-five degrees in this country, better than red clover. 9. _Long-rooted Clover._--This is a Hungarian variety--biennial, but resows itself several years in succession, on good, clean land. Its yield of hay and seed is abundant. Needs a deep, dry soil, and stands a drought better than any other grass. To plow in as a fertilizer, or for soiling cattle, it is valuable, wherever it will flourish. 10. _Sain-Foin._--Adapted to calcareous or chalky soils; considered one of the best plants ever introduced into England; but in New England it proves almost a failure--it requires more cool moisture and less frost. 11. _Timothy._--In England, _Meadow Cats'-tail_, and in New England, _Herd's-grass_. This is the most valuable of all the grasses, and wherever it will thrive well, should never be superseded by anything else for hay. It should be cut when the seed has begun to harden, but before it begins to shell, and never in the blossom. Let every farmer remember that timothy, cut in the seed, contains twice as much nutriment as when cut in the blossom; hence, it is not worth more than half as much for hay, sown among clover, as when sown by itself, as it must be cut too early, to avoid losing the clover.
