Mammoth clover {T. medium L.). — Two plats, lO-F-8 and 9, were planted 

 ^lay 29. This germinated quickly and grew well, showing but little effect of 

 the drought. By October 16 the plants were 2 feet high and seeding well, but 

 were beginning to die. November 17 the most of the foliage was dead but no 

 injury had been done by frost. 



Strawberry clover [T. fragifermn L.).— Plat 10-F-l was sown May 29 with 

 Russian seed (S. P. I. No. 1018). On June 19 the first plants appeared. These 

 grew slowly during the summer, showing no injury by heat. On October 16 the 

 plants were in vigorous healthy condition, 5 to 6 inches high, making a thick, 

 close growth. No flowers were produced. November 17 a few of the younger, 

 tenderer leaves were killed by frost but the mass of the foliage was not injured. 



Bush clover (Le.y>edeza sp.).— Plats lO-F-14 and 15 were planted May 29 with 

 Japanese seed of L. seriaea Benth. (S. P. I. No. 3121). The plants came up 

 thinly and grew steadily through the hot spell, reaching a height of 2 feet in 

 October. The plant is perennial, erect, with slender ascending branches, short, 

 sessile leaves and white flowers borne sessile on the main stem and branches, 

 nearly hidden by the numerous small leaves. The stems are tough and woody, 

 but aside from this the plant should make good forage if palatable. 



Another species {L. bicolor Turcz.) called "Hagi" in Japan (S. P. I. No. 2923) 

 was planted May 29 on plats lO-F-16 to 18. It grew very much as the preceding 

 but attained to the larger size of 3 feet. This species is very much branched 

 with longer silky leaves, and flowers in an open terminal panicle. It has much 

 more foliage in proportion to the stems and branches and would make more and 

 better forage. It is also a perennial. The leaves were mostly killed by frost in 

 November, by which time most of the seed was ripe. 



Bird's-foot clover (Lof^fs comiculatus L.).— A half plat, 10-G-3a, was sown 

 with Russian seed (S. P. I. No. 1065) on May 31. Only a few plants came up, 

 but by their prostrate habit they soon covered the surface of the groiind. By 

 August 3 the plants were about 18 inches across and buds were appearing. 

 September 20 the plants measured 2| feet in diameter and were covered with 

 bunches of bright yellow flowers. A month later these had disappeared and 

 the seed was neai-ly ripe. The younger leaves were killed by November frosts, 

 but the plat still looked green and fresh. 



This little plant is highly e-^teemed in Europe for use on light, sterile soils and 

 in dry places. It has become naturalized in the Southern States. The foliage 

 is relished by both cattle and sheep. 



Swamp lotus (Lotus uliginoms Schkuhr.).— A two thirds plat, 10-G-2b, of 

 this was started with French seed (S. P. I. No. 1468) on May 31. A fair stand 

 resulted and the plants grew slowly until the heat of July checked them for a 

 time, burning the tender foliage somewhat. On September 20 they were 6 

 inches high, healthy, and beginning to flower. Growth continued but no seed 

 set. Frost killed only the more delicate yoiing leaves. 



The swamp lotus is a native of northern Europe, where it is valuable for wet 

 or swampy land. It has been used successfully in similar places in the northern 

 United States. 



Sulla {Hedysarum coronarium L.). — Plat lO-G-4 was planted May 31 with 

 Division seed and plats lO-G-5 to 7 on the same date with French seed (S. P. I. 

 No. 1518). A good stand of each was secured by June 11. July 6 the plants 

 were about 3 inches high and noticeably affected by the dry weather, from 

 which they recovered only slowly. In Augiist rapid, vigorous growth com- 

 menced, and by October 16 they were over 1 foot high and quite healthy in 

 appearance. November 18 found them 18 inches in height and but little injured 

 by frosts.
