t&ifve and long-lived dwarf tree,- provided the graft- 
ing Is done with a very early variety. This shrub 
occurs in extremely hot, dry places and must therefore 
complete the greater part of its development early in 
the season; Its roots are unable to furnish the amount 
of sap necessary to develop pears in August. If it 
is grafted with a pear which fruits in May or June, 
when the roots of the Crataegus are in the period of 
their greatest activity, the best results are obtained. 
The writer speaks only of pears, because he has ex- 
perimented with them, but he sees no reason a priori 
why these stocks should not do as well for apples , which 
he has not as yet tried. (Adapted from Bureau of Plant 
Industry Bulletin No. 180, p. 15.) 
Crataegus mexicana (Malaceae), 48507. Prom Guada- 
lajara , Mexico . Seeds presented by Mr. F. S. Furnivall 
through the American consul. "White-thorn, commonly 
known as the manzanllla or tejocote, is indigenous to 
the mountain section of Mexico and Guatemala ; the fruit 
(a little apple about the size of the American crab- 
apple) is insipid in flavor In the raw state, but very 
valuable for making jelly; the tree or shrub may be 
used with marked success as a stock in budding and 
grafting apples and pears." (Furnivall.)

Eremoehloa ophiuroides (Poaceae), 48566. Grass. From 
Kuliang Hills, near Foochow, Fukien, China. Collected 
by Mr. J. B. Norton, agricultural explorer. "The best lawn 
and grazing grass of this region. Throughout the clay 
region and the gravelly sand alluvial this is the 
dominant grass. All the neglected fields and washed 
hillsides are overgrown with it. It is valued in 
Kuliang and largely in Foochow as a grass for lawns. 
If the lawns are mowed, clipped, or grazed, this Is 
the only grass which persists except Bermuda grass 
which sometimes maintains itself along the edges of 
walks and paths. This grass in pure culture does not 
need to be mowed as it grows only 3 or 4 Inches high. 
It can be eradicated easily as the runners are on the 
surface; and it is easily propagated by pieces of run- 
ners, turf, or seed. It is the best grazing grass in 
this region, growing with Lespedeza striata and allied forms 
over the fallow terrace lands. The prime condition 
of the cattle grazing on these hills depends on the
