LESPEDEZA 



but on heavy lands grows 18-24 in. high. It is a good 

 pasture-and bay-plant, and is useful for plowing under 

 as a green manure. It thrives on land which is indiffer- 

 ently prepared. For hay, seed is sown early in spring, 

 at the rate of K bushel per acre. It often yields 2 tons 

 of hay to the acre. For pasturage in the South, it is 

 sometimes sown with oats In the fall.

 branches, becoming 6-10 ft. tall, slender and graceful, 

 glabrous: Ivs. on thin wiry stalks, mostly longer than 

 the glabrous blades ; Ifts. oval to round -obovate, rounded 

 at the apex, the terminal one 1-2 in. long: fls. small, 

 purple, in simple or compound racemes, which surpass 

 the Ivs.: pod 5i in. long, somewhat pubescent. Japan. 

 — Hardy as far north as Boston, blooming in July and 

 seeding freely. A good slender shrub for adding va- 

 riety to the border. A white-fld. variety is advertised.

LETTSOMIA is a genus of the Convolvulus family. 

 About 26 species of tropical oriental climbers. An un- 

 known species was advertised from S. Florida in 1889 

 and is still procurable. Reasoner and others think well 

 of it. 



LETTUCE (see Lactuca) is the most popular of salad 

 vegetables. Plate XVIII. It is a quick-growing annual, 

 delighting in cool atmosphere and open, loose soil. As 

 an outdoor crop, it thrives best in spring. Special care 

 is needed to grow it in the hot summers of America, al- 

 though heat-resisting varieties have been developed. Of 

 late years, the forcing of Lettuce under glass has come to 

 be a large industry. The most serious trouble in forcing 

 Lettuce is the rot, due to a species of botrytis. The 

 leaves become soft and fall, leaving only the core of the 

 plant erect (Fig. 1265). This trouble may be prevented 

 by growing in loose soil, by keeping the surface of the

Lettuce OrT-OF-DooRS.- While Lettuce seems never 

 more enjoyable than when it comes from the greenhouse 

 during the colder parts of the year, yet it is acceptable 

 for salad purposes and is in good demand the entire 

 year. In open ground, at the North, we may have it in 

 all its perfection from June until snow flies again in the 

 fall, tfsually it is much less of a knack, however, to 

 have it in the earlier part of the season and up to 

 August, than in the torrid weather of August and early 

 fall. For early market we start the plants in the green- 

 house during February, and prick them out in flats or 

 sunken thurab-pots filled with rich, fibrous loam, and 

 after thoroughly hardening them by exposure for a week 

 or more in a coldframe, we take the plants up, with a 

 chunk of soil, and plant them out in very rich, well- 

 prepared loam outdoors, just as soon as the weather 

 will permit. Tennisball and its various strains and 

 selections. Boston Market, etc., are good for this pur- 

 pose. The rows may be made a foot apart, and the 

 plants set 6 or 8 inches apart in the rows. We want neat 

 solid heads, even if not as large or heavy as some of the 

 heads we can easily produce later on from summer 

 varieties, and we wish to get them as early in the season 

 as possible in order to be able to put them on the mar- 

 ket when prices are still high. Light applications of 

 nitrate of soda, either broadcast over the patch at the 

 time of setting the plants, or along the rows very soon 

 after, seldom fail to assist in hastening early growth 

 and to increase the size of the heads. This is a "trick of

the trade" well worth practicing. The free use of the 

 wheel-hoe keeps the soil loose and the crop free from 

 weeds, and also hastens it to early market condition. 



At the time of setting the first plants in open ground, 

 we also sow a patch with the garden drill, using seed
