other birds have darted to the feast--the starlings alight among the plumes of the laburnum, interrogating in acidulous tones, their black, burnished, iridescent feathers and flame-hued eyes making a picture of rare vividness and beauty.
How thin becomes the throng! Last night's shower, the morning warmth of the soil, have brought forth a gush of life that wheels and sparkles in the sun and becomes bait for birds. Are droughts designed by Nature to test endurance on the part of animal and vegetable life? Leaves fall from evergreen trees almost as completely as from the deciduous, and even the jungle is thickly strewn, while every slight hollow is filled with brittle debris where usually leaves are limp with dampness and mould. The jungle has lost, too, its rich, moist odours. Whiffs of the pleasant earthy smell, telling of the decay of clean vegetable refuse, do issue in the early morning and after sundown; but while the sun is searching out all the privacies of the once dim area, the wholesome fragrance does not exist.
Drought proves that certain species of exotic plants are hardier than natives. Wattles suffer more than mangoes, and citrus fruits have powers of endurance equal to eucalyptus. Whence does the banana obtain the liquid which flows from severed stem and drips from the cut bunch? Dig into the soil and no trace of even dampness is there; but rather parched soil and unnatural warmth, almost heat. Heat and moisture are the elements which enable one of the most succulent of plants to bear a bunch of fruit luscious and refreshing, and when heat alone prevails, the wonder is that the whole patch of luxuriant greenness does not collapse and wither. But the broad leaves woo the cool night airs, and while the thin, harsh, tough foliage of the wattles becomes languid and droops and falls, the banana grove retains its verdancy, each plant a reservoir of sap.
A noteworthy feature of the botany of the coast of tropical Queensland is its alliance with the Malayan Archipelago and India. Most of the related plants do not occur in those parts closest to other equatorial regions in the geographical sense, but in localities in which climate and physical conditions are similar. Probably there are more affinities in the coastal strip of which this isle is typical than in all the rest of the continent of Australia. One prominent example may be mentioned-viz., "the marking-nut tree." When the distinctiveness of the botany of the southern portions of Australia from that of the old country began to impress itself on the earliest settlers, the miscalled native cherry was the very first on the list of reversals. The good folks at home were told that the seeds of the Australian cherry "grow on the outside." The fruit of the cashew or marking-nut tree betrays a similar feature in more pronounced fashion. The fruit is really the thickened, succulent stalk of the kidney-shaped nut. The tint of the fruit being attractive, unsophisticated children eat of it and earn scalded lips and swollen tongues, while their clothing is stained indelibly by the juice. Botanists know the handsome tree as SEMECARPUS AUSTRALIENSIS, but by the indignant parent of the child with tearful and distorted features and ruined raiment it is offensively called the "tar-tree," and is subject to shrill denunciations. The fleshy stalk beneath the fruit is, however, quite wholesome either raw or cooked, but the oily pericarp contains a caustic principle actually poisonous, so that unwary children would of a certainty eat the worst part. The tree, which belongs to the same order as the mango, has a limited range, and there are those who would like to see it exterminated, forgetful that in other parts of the world the edible parts are enjoyed, and also that a valuable means to the identification of linen is manufactured from it. A tree that is ornamental, that provides dense shade, that bears pretty and strange fruit, an edible part, and provides an economic principle, is not to be condemned off-hand because of one blot on its character.
An Indian representative of the genera produces a nut which when roasted is highly relished, though dubiously known as the coffin-nail or promotion nut, but there is no reason to believe that it is specially indigestible unless eaten in immoderate quantity.
One of the many bewilderments of botany is that plants of one family exhibit characteristics and habits so divergent that the casual observer fails to recognise the least signs of relationship. Similar confusion arises in the case of plants of the same species producing foliage of varied form. One of the figs (FICUS OPPOSITA) displays such remarkable inconsistency that until reassured by many examples it is difficult to credit an undoubted fact. The typical leaf is oblong elliptical, while individual plants produce
