Tripsacum dactyloides Linn. Gama-grass; Sesame-grass; Bull-grass. (Fig. 87.) 
A tall, coarse perennial, 3 to 8 feet high, growing in large tufts, and producing a 
eat mass of broad leaves, which when young and succulent are eaten wi 
avidity by all kinds of stock. When abundant it affords a large amount of 
natural forage, and is valuable to this extent. It has very strong, creeping 
rootstocks, and the quantity of forage produced is large and of excellent quality. 
The grass may be deserving of cultivation for forage under certain conditions, 
and it makes an interesting and attractive plant for lawn decoration or the gar- 
den. A rich and rather moist soil is best suited to it.

drought-resisting qualities. Its habit of growth and purplish heads render it

Trisetum pratense Pers. Yellow Oat-grass; Golden Oat-grass. 
A rather slender, loosely tufted perennial, growing to the height of 2 feet. It is a 
ative of Europe, northern Africa, and western Asia. It qa along roadsides, 
in open fields, aud on grassy monntain slopes, where its presence is said to 
indicate land of good quality. In Europe Yellow Oat-grass is classed with the 
best fodder plants and is highly valued for temporary, but more particularly for 
permanent pastures, It can be grown on almost every variety of soil, is fairly 
productive, and is readily eaten by stock. This grass has a record of yielding 
on clayey loam soils 8,167 pounds green grass, 2,858 of hay, and 4,083 of after- 
math. In this country it has received little attention. It is quoted in New 
York seed R the price ranging from $70 to $115 per 100 pounds. Sown
