Brazil has three groups of animals similar to the common rat - the Capromydae, Loncheridae and Psammoryctidae- the best known of which is the " tuco-tuco " (Ctenomys brasiliensis), a small burrowing animal of Rio Grande do Sul which excavates long subterranean galleries and lives on roots and bulbs.

These pheasant's-eye narcissi, of which there are several well-marked varieties, as radiiflorus, poetarum, recurvus, &c., blossom in succession during April and May, and all do well in the open borders as permanent hardy bulbs.

Thousands of bulbs of such lilies as longiflorum and speciosum are now retarded in refrigerators and taken out in batches for greenhouse work as required.

The spores formed on the delicate grey mould are carried during the summer from one plant to another, thus spreading the disease, and also germinate in the soil where the fungus may remain passive during the winter producing a new crop of spores next spring, or sometimes attacking the scales of the bulbs forming small black hard bodies embedded in the flesh.

For prevention, the surface soil covering bulbs should be removed every autumn and replaced by soil mixed with kainit; manure for mulching should also be mixed with kainit, which acts as a steriliser.

Rhizopus necans is sometimes the cause of extensive destruction of bulbs.

The fungus hibernates in the soil and enters through broken or injured roots, hence care should be taken when removing the bulbs that the roots are injured as little as possible.

This prevents infection from outside and also destroys any spores or fungus mycelium that may have been packed away along with the bulbs.

Not only are millions of bulbs cultivated in Holland for export every year, but thousands are now also grown for the same purpose in the Channel Islands, more particularly in Guernsey.

The enormous prices once given for rare varieties of tulip bulbs no longer obtain, though, even now, two and three guineas are asked for special bulbs.

The breeder bulbs and their offsets may grow on for years producing only self-coloured flowers, but after a time, which is varied and indefinite, some of the progeny "break," that is, produce flowers with the variegation which is so much prized.

The best time to plant is in September and October, the bulbs being buried about 6 in.

Sometimes a little loose earth or sand is put in to the depth of about I in., and the bulbs laid singly thereon, the holes being closed by the dibber and the whole raked over.

The tops can then be removed and the bulbs sorted and stored thinly in trays in a cool dry place.

Rare bulbs may be wrapped singly in tissue paper for storing.

Pot firmly, and plunge the pots in several inches of ashes out of doors, to protect the bulbs from frost.

The bulbs are placed in long shallow boxes, plunged in soil or ashes in the open air, and are later introduced as required into heat in semi-darkness, and are afterwards transferred to benches in the forcing houses where they flower.

Bulbs which have been forced are of no further value for that particular purpose.

The vulva or pudendum comprises all the female external generative organs, and consists of the mons Veneris, labia majora and minora, clitoris, urethral orifice, hymen, bulbs of the vestibule, and glands of Bartholin.

Thomson 6 places spherical bulbs inside thick spiral conductors through which the oscillating discharge of a powerful battery is led.

About the beginning of September the crop is ripe, which is known by the withering of the leaves; the bulbs are then to be pulled, and exposed on the ground till well dried, and they are then to be put away in a store-room, or loft, where they may be perfectly secured from frost and damp.

Those which are not required for the kitchen, if allowed to stand, and if the flower-bud is picked out on its first appearance, and the earth stirred about them, frequently produce bulbs equal in size and quality to the large ones that are imported from the Continent.

A crop of very large bulbs may also be secured by sowing about the beginning of September, and transplanting early in spring to very rich soil.

Another plan is to sow in May on dry poor soil, when a crop of small bulbs will be produced; these are to be stored in the usual way, and planted in rich soil about February, on ground made firm by treading, in rows about 1 ft.

To obtain a crop of bulbs for pickling, seed should be sown thickly in March, in rather poor soil, the seeds being very thinly covered, and the surface well rolled; these are not to be thinned, but should be pulled and harvested when ripe.

It is also known as the underground onion, from its habit of producing its bulbs beneath the surface.

These small stem bulbs are excellent for pickling.

It forms no bulbs, but, on account of its extreme hardiness, is sown in July or early in August, to furnish a reliable supply of young onions for use in salads during the early spring.

These bulbless onions are sometimes called Scallions, a name which is also applied to old onions which have stem and leaves but no bulbs.

On the other hand, a current of dry air may be passed through the series of weighed bulbs containing solution and solvent respectively, and the loss in weight of each determined.

The loss in the solution bulbs gives the mass of solvent absorbed from the solution, and the loss in the solvent bulbs the additional mass required to raise the vapour pressure in the air-current to equilibrium with the pure solvent.

The relative lowering of vapour pressure of the solution compared with that of the solvent is measured by the ratio of the extra mass absorbed from the solvent bulbs to the total mass absorbed from both series of bulbs.

For commercial purposes, crowns of lily of the valley, tulip and other bulbs, and such deciduous woody plants as lilac and deciduous species of rhododendron, while in a state of rest, are packed in wet moss and introduced into coldstorage chambers, where they may be kept in a state of quiescence, if desired, throughout the following summer.

River sand and the sharp grit washed up sometimes by the road side are excellent materials for laying around choice bulbs at planting time to prevent contact with earth which is perhaps manure-tainted.

Hyacinths and other bulbs derive benefit from slight doses, while to asparagus as much as 20 lb to the rood has been used with beneficial effect.

This mode of increase applies specially to bulbous plants, such as the lily and hyacinth, which produce little bulbs on the exterior round their base.

Most bulbs do so naturally to a limited but variable extent; when more rapid increase is wanted the heart is destroyed, and this induces the formation of a larger number of offsets.

The stem bulbs of lilies are similar in character to the offsets from the parent bulb.

The same mode of increase occurs in the gladiolus and crocus, but their bulb-like permanent parts are called corms, not bulbs.

This mode of potting does well for bulbs, such as hyacinths, which are either thrown away or planted out when the bloom is over.

Most of the hardy bulbs will do well enough in the border, care being taken not to disturb them while leafless and dormant.

Hardy bulbs of the garlic family, some species of which are ornamental; the inflorescence is umbellate.

The Snowdrop. Early spring-flowering amaryllidaceous bulbs, with pretty drooping flowers, snow-white, having the tips of the enclosed petals green.

A genus of South African plants with fibrous-coated corms or solid bulbs, often known as montbretas.

Splendid dwarfish bulbs, thriving in deep, sandy, wellenriched garden soil, and increased by offsets.

Besides these there are the various spring-flowering bulbs, such as the varieties of Hyacinthus, Tulipa, Narcissus, Fritillaria, Muscari or Grape Hyacinth, Crocus, Scilla, Chionodoxa and Galanthus or Snowdrop.
