Humble Bee—continued. 
Bees become really injurious, their numbers are most easily 
lessened by the destruction of their nests, which will be 
found under moss or stones, or in holes in the ground.

HUMEA (named after Lady Hume, once of Worme- 
leybury, Herts). Syns. Agathomeris, Calomeria. ORD. 
Composite. A genus comprising four species of herbs or 
shrubs, limited to Australia. Flower-heads small and 
numerous, in a loose terminal panicle, or in compact 
corymbs. Leaves alternate, quite entire. The best- 
known and most frequently cultivated species is H. 
elegans, a very ornamental plant, when well grown, for 
greenhouse decoration or sub-tropical gardening. It is 
a biennial. The seed should be sown in July, in light, 
finely-sifted soil, and placed in any cool frame. When the 
plants appear, they should be potted, taking care not to 
injure the roots. Grow on in a frame or cool house, where 
plenty of light and air are available, and keep the roots 
nearly dry throughout the winter. In spring, gradually 
encourage growth, and pot on, placing into about 9in. 
pots as a final shift. The plants seldom succeed, unless 
very carefully treated in potting and watering. They 
do not like syringing, unless when growing strongly in 
warm weather. Being tender, they must not be planted 
outside before June, and must then be staked and pro- 
tected from rough winds. A rich soil, composed of loam 
and decayed manure, with a little. cine should — 
be used, when potting, after the young ts are once 
established. . > = a.

if not supported). . Hop. ORD. Urticaceæ. A genus con- S 
taining a couple. of species of ornamental hardy peren- 
nial twiners, of. easy culture in ordinary garden soil, but 
thriving best in a deep loam. H. Lupulus is a vigorous — 
and quick-growing plant; the second species is a native 
of China, Japan, &c. Propagated by seeds, or by divi-
