Another way, and the easiest, to have a constant succession of lettuce for the table throughout the season, is to sow the seed thickly in drills and to cut the loose leaves close to the ground when it is three or four inches high; this produces rather narrow leaves, which are very tender and juicy, but which have not the substance of those grown as separate plants or heads, and are not so easily prepared for the table. These sowings can be made every few weeks, and a constant succession of young leaves be had for use throughout the entire season. It should be the object in sowing lettuce to plant small lots frequently, that it may always be had in the best condition. About the second week in September a sowing of some early hard-heading variety should be made, and a succeeding one about the first of October; from these two sowings the cold frames should be planted, about one-third from the first and two-thirds from the second; the plants should be set about six inches apart each way, which will allow about fifty plants to each sash. When cold weather comes the sash should be put on, and the outsides of the frames banked around with long stable manure. The plants must be treated to plenty of fresh air whenever the weather will permit of it, and on very cold nights the sash should be reinforced with a covering of straw, old mats, or carpet. The lettuce grown in these frames is apt to be infested with the small insect known as the “Green Fly;” to prevent or to get rid of the presence of this pest, tobacco refuse and sweepings from a cigar-maker’s shop should be strewn on the soil under the leaves; this will destroy the fly and act as a fertilizer, but if too much is applied it will spoil the delicate flavor of the lettuce. If a few very early cabbages are desired, the seed should be sown about the first of October and transplanted with the lettuce into the cold frames; planting them about two inches apart each way; if these are in good condition and the spring favorable, they can be planted out about the 15th of March, and will produce heads one to two weeks earlier than those raised in the hotbeds. VARIETIES OF LETTUCE. BURPEE’S HARD-HEAD.--This is the fastest growing and the best heading kind that I have ever grown. With this variety the ordinary gardener is able to grow as fine, large, solid heads as those grown by the professional market gardener. In shape it very much resembles a cabbage, as even the outer leaves tend to curl in over the head, instead of spreading outward, as in most lettuces. In appearance it is quite novel and striking, the edges of the leaves being tinged with a deep brownish-red, while in the centre of its hard heads the leaves are blanched to a beautiful creamy white. In quality it is remarkably tender, rich, juicy, and never bitter. [Illustration: BURPEE’S HARD-HEAD LETTUCE.] [Illustration: BURPEE’S TOMHANNOCK LETTUCE.]
