Grafting is a horticultural operation which consists in placing together the two cut surfaces of different plants in such a way that they shall unite and become an organic unity. The rooted plant which is to receive the graft is called the 'stock'; the cutting which is to be applied to the stock, and to obtain its nourishment from it, is called the 'scion'. This illustration shows Terminal Herbaceous grafting.

In the manufacturing of jute, the jute fiber must first be softened. The softening machine consists of many pairs of fluted or corrugated rollers arranged in horizontal succession and driven with a reciprocating motion. The jute as it passes through may receive a sprinkling of oil ad water from automatic apparatus attached to the machine overhead, or it may be arranged in the layers and sprayed with oil after emerging from the softener, a process known as batching. In either case, the material is then allowed to lie a certain time in bulk, to permit of the fiber being thoroughly permeated with the oil.

After the softening process in the manufacturing of jute, the fibers are about six feet long, and are passed onto the breaker card, where they are reduced in length, finely divided, thoroughly mixed, cleared of impurities, and laid in parallel order. The chief features of the card are a cylinder about four feet in diameter covered with wooden staves filled with steel teeth, and around this cylinder a number of smaller cylinders, known as strippers and workers, also covered with steel teeth. The jute fibers are carried around the large cylinder, being finely divided by the workers and strippers in their course. A doffer roller then strips the elongated lap from the main cylinder and sends it down a broad channel, which compresses it to a strand or sliver about four inches wide. Twelve of these slivers are then fed into the finisher card, which is similar to the breaker, but has finer teeth, and are drawn out into a finer, smoother strand.

In the last step of the manufacturing process of the jute plant, the material is taken on bobbins to spinning frames of the throstle type, and spun into yarn of various sizes, with a hard twist for warps and a softer twist for wefts. The warp yarns on bobbins are then passed on to the spooling and dressing machines, or are reeled in hanks and bundles for the purpose of being bleached or dyed in various colors for stripes in the fabric to be woven. The weft yarns are taken to the cop winding machines.

Jute, also known as Calcutta Hemp, is a fiber obtained from several species of the genus Corchorus of the order Tiliaceæ, and employed in the manufacture of the coarser textiles. The great bulk of the world's supply is derived from two species, C. capsularis and C. olitorius (Jew's Mallow), both of which are indigenous to Bengal, India, where from remote times they have been cultivate for economic purposes. The two species are similar in appearance, but may be distinguished by the form of the seed pods, which are nearly spherical in C. capsularis, and long and narrow in C. olitorius. Both plants are herbaceous annuals with straight, slender stalks from 5 to 15 feet in height, branched at the top, and bearing small yellow flowers. The fiber, which is derived from the inner bark, is of a creamy yellow or light buff color and of a silky luster. It spins well, but is not as strong as flax or hemp, and deteriorates rapidly. The young shoots are used as pot herbs. Jute is grown chiefly in Bengal, though it is raised to a limited extent in China, Formosa, and Southern Japan. It can be grown successfully in the South Atlantic and Gulf States of the United States, but lack of mechanical methods for preparing the fiber has prevented its cultivation on an industrial scale. Attempts to naturalize it elsewhere have generally failed. For its most successful cultivation, jute requires a soft, deep soil and a hot, moist atmosphere, alluvial lands being especially adapted to its production. This illustration shows Corchorus capsularis.

The lady fern in the popular name of the fern 'Asplenium filix-foemina'. It is variable in size and detail, of very graceful habit, and of thin, almost transparent texture, with conspicuous venation. Its color is a most delicate green. The fronds are lanceolate and bipinnate, and are developed from the summit of the caudex. Many varieties are found wild, such as 'marinum', whose fronds taper from their centers toward either extremity; 'latifolium'; and 'convexum', whose fronds are much narrower than in the common type. The lady fern and its varieties are easily cultivated in any damp, shady spot.

Laminaria saccharina belongs to the group Laminariæ, a group of algæ belonging to the Phæosporeæ, a subdivision of the Phæosphyceæ, or brown seaweeds. The propagative cells are always swarm-spores of similar form and size; and these are produced in unilocular sporangia. The thallus has a stalk, often of considerable thickness, which is attached below to rocks or other substratum by means of rootlike growth, and ends above in a flat lamina, which may be divided or undivided.

Lamium album (also known as the white dead-nettle, or archangel) is a member of the Lamium, a genus of Labiatæ, whose flowers are marked by possessing four stamens longer than the corolla tube, a bell-shaped calyx with five teeth, and a two-lipped corolla, the upper lip being arched, the lower trifid and spreading. It has been naturalized in America and has a square stem and white flowers with black stamens.

Larch, or Larix, is a genus of hardy, deciduous, coniferous trees of very graceful habit. They bear monoecious flowers, the male catkins being small and oval, whilst the female ones are much longer. The leaves are bright green, linear, soft, and usually produced in short bundles on each side of the spray. They appear very early in the spring. The timber, which is very hard and tough, is much used in shipbuilding and for railway sleepers, and in cabinet work is capable of taking a very high polish. The species most commonly planted is 'L. europaea', whcich grows to about 100 ft in height. Other species are 'L. occidentalis', a tall and handsome American tree and 'L. laricina', the tamarack, or hackmatack, of North America. This is a straggling tree, most common in swampy soils, with smaller cones than has the the European species. It reaches a height of 70 ft., and the wood is valuable for the same purposes as that of other larches. (1. Scale of cone with two seeds; 2. anther)

Lattice Leaf is the popular name of a water plant, 'Aponogeton jenestralis', belonging to the order 'Aponogetonaceæ'. The older leaves are of open structure, are nearly a foot long, oblong in shape, and float just below the surface of the water. The flowers are born in spikes in the surface. The roots of the plant are used as an article of food by the natives of Madagascar, where it is indigenous. (1. Part of Flower Spike)

Layering is a method of plant propagation by which a part of the plant is bent down and covered with soil, so that it may emit roots before being separated from the parent plant. in some instances, it is sufficient to remove all buds from the shoot, with the exception of a few near its extremity, and to bend it and peg it down so that a part of its proximal end is buried beneath the soil. In others it is necessary partly to cut through the stem at the point where it is to be covered with soil.

This illustration shows a lentil plant. Lentils are the round, flat seeds of a small leguminous plant <i>(Vicia (Lens) hirsuta)</i>, of which numerous varieties are cultivated in the countries bordering the Mediterranean and elsewhere. The seeds are highly nitrogenous, and of great food value. They form the principal constituent of the well-known <i>Revalenta arabica</i> of commerce. They consist of -- starch, 50 percent; casein, 24 percent; fat, 2 percent; and water, 14 percent. The dark green German lentils are much more palatable than the reddish-yellow Egyptian variety.

This illustration shows a portion of Lepidodendron. Lepidodendron is the generic name of a large and important group of plants which flourished principally in the Carboniferous period. The outer surface of the bark is marked by lozenge-shaped, scale-like markings, the leaf-cushions. These are arranged in dense spirals, which wind around the stems. Often, the narrow and pointed leaves are found, still adherent; they may also carry cones <i>(lepidostrobi)</i>, which in form somewhat resemble those of the fir. The branches usually fork repeatedly, and were implanted on a massive stem which had a similar external sculpture. Some of these stems have been seen in the roofs of coal workings with a length of a hundred feet. Their roots are generally known as stigmaria. The Lepidodendra belonged to the Lycopodiaceæ, and have their nearest representatives in the diminutive club-mosses, which they resemble even in their superficial characters.
