HYACI'NTHUS. The Hyacinth. (In 

 mythology, a beautiful boy, who, after 

 being killed, was transformed into this 

 flower. Nat. ord., Lily worts [Liliacese]. 

 Linn., 6-Hexandria \-Monogynia.} 



Offsets from the bulbs, after the foliage has 

 died down in summer ; light, rich, sandy loam, 

 with a little leaf-mould. A valuable bulb for 

 forcing. Best florists' kinds grown out of doors, 

 should be taken up after the foliage is withered, 

 kept in shelves and drawers until the end of au- 

 tumn, and then planted and protected from severe 

 frost in winter, and frost and heavy rains in 

 spring, by an awning. For a brilliant out-door 

 display, where the kinds are not so valuable, the 

 roots may remain in the ground many years if 

 top-dressed, and the balbs are not too near each 

 other. When grown in pots, these should be 

 deeper than usual, in proportion to the diameter- 

 nine inches are not too much. The compost we 

 have found most suitable for them in pots is a 

 "good loam, three-fourths, and decayed cow-dung, 

 'two years old, one-fourth. In October they ought 

 to be potted, and immediately plunged in tan or 

 .ashes, quite overhead, at least two inches. In 

 potting, make the soil very firm under the bulb, 

 to prevent the roots going directly down too soon. 

 In a month after potting and plunging, a few 

 may be brought into heat, and forced to flower 

 .about Christmas ; and others may be brought in, 

 month after month, to supply flowers till May. 

 To grow them in water, glasses with a hollow cup 

 at the top, to hold the bulb, are used. It is not 

 good to begin too soon with glasses. December 

 is quite early enough. After being kept for a few 

 <l*ya in slightly-damped sand, they should be 



placed in their glasses. At first the water should 

 only just touch the base of the bulbs, and the 

 glasses should be kept in a dark closet until the 

 roots have attained the length of an inch. Two 

 drops of spirit of hartshorn may be added to the 

 water in each glass when the bulbs are growing, 

 and whenever the water is changed. Dark-coloured 

 glass is always to be preferred, as the absence of 

 light is natural to all roots. By keeping the 

 glasses in a dark closet until the roots are full an 

 inch long, the hyacinths will not get top-heavy, 

 but the roots, being in advance of the leaves, will 

 preserve the plant balanced erect. The bloom 

 will also be finer, as the roots will be in a state to 

 nourish the leaves before these are prematurely 

 advanced. A piece of charcoal put into each glass 

 feeds the plant, andprevents putridity in the water.

HYBRIDIZING, or CROSS - BREEDING, 

 though not quite identical, have with the 

 gardener similar objects, viz., either im- 

 proving the beauty of his flowers, or the 

 flavour and prolificacy of his fruits and 

 culinary products. Hybridizing, strictly 

 speaking, is obtaining a progeny between 

 two different species, by fertilizing the 

 stigma of one with the pollen of another; 

 and cross -breeding is obtaining a progeny 

 between varieties of the same species. 

 The progeny of hybrids cannot produce 

 seed; but cross-breds are fertile. Our 

 own observations, and those of others, 

 justify the following statements, as afford- 

 ing some guide to the raiser of varieties: 



1. The seed-vessel is not altered in 

 appearance by impregnation from another 

 plant ; therefore, no hasty conclusion of 

 failure is justified by that want of change. 



2. The colour of the future seed, not
