is upon an average 5 degrees lower in the morning, and the same number of degrees higher at noon throughout the winter season, but during the summer months it is 5 degrees higher at all hours of the day. On the mountains themselves, and in the country to the westward of them, the climate, in consequence of their superior elevation, is much more temperate. Heavy falls of snow take place during the winter, and remain sometimes for many days on the summits of the loftiest hills; but in the valleys the snow immediately dissolves. The frosts too are much more severe, and the winters are of longer duration. All the seasons indeed are more distinctly marked to the westward of the mountains, and bear a much stronger resemblance to the corresponding ones in this country.

From the foregoing account of the state of the weather and temperature during the various seasons of the year, it will be seen that the climate of the colony is upon the whole highly salubrious and delightful. If the summers are occasionally a little too hot for the European constitution, it will be remembered that the extreme heats which I have noticed as happening during the north-west winds, are of but short continuance; and that the sea and land breezes, which prevail at this season in an almost uninterrupted succession, moderate the temperature so effectually, that even new comers are but little incommoded by it, and the old residents experience no inconvenience from it whatever. The sea breeze indeed is not so sensibly felt in the interior as on the coast, by reason of the great extent of forest which it has to traverse before the inhabitants of the inland districts can receive the benefit of it. This circumstance not only diminishes its force, but also deprives it in a great measure of that refreshing coolness which it imparts when inhaled fresh from the bosom of the ocean. The heat consequently in the interior, particularly in low situations, is much more intense than on the coast; but by way of compensation for the advantage which in this respect the districts in the vicinity of the sea possess over the inland ones, these latter are from the same causes that impede the approach of the sea breeze, exempt from the sudden and violent variations of temperature, which are occasioned by the southerly winds, and are without doubt the reason why pulmonic affections are so much more prevalent in Sydney than in the interior. The hot season, however, which is undoubtedly the most unhealthy part of the year, does not, as will have been perceived, continue above four months. The remaining eight possess a temperature so highly moderate and congenial to the human constitution, that the climate of this colony would upon the whole, appear to justify the glowing enthusiasm of those who have ventured to call it the Montpellier of the world.

Abdominal and pulmonic complains are the two prevalent diseases. The abdominal complaints are confined principally to dysentery. This disorder is most common among the poorer classes and new comers. In these it is generally intimately connected with scurvy, and in both cases it is for the most part greatly aggravated by the excessive use of spirituous liquors, to which the mass of the colonists are unfortunately addicted.

The pulmonic affections are generally contracted at an early period by the youth of both sexes, and are occasioned by the great and sudden variations of temperature already noticed. They are not, however, accompanied with that violent inflammatory action which distinguishes them in this country; but proceed slowly and gradually, till from neglect they terminate in phthisis. They are said to bear a strong affinity to the complaint of the same nature which prevails at the Island of Madeira; and it is remarkable, that in both these colonies a change of air affords the only chance of restoration to the natives; whereas foreigners labouring under phthisis upon their arrival in either of these places, find almost instantaneous relief.

There are no infantile diseases whatever. The measles, hooping cough, and small pox, are entirely unknown. Some few years, indeed, before the foundation of this colony, the small pox committed the most dreadful ravages among the aborigines. This exterminating scourge is said to have been introduced by Captain Cook, and many of the contemporaries of those who fell victims to it, are still living; and the deep furrows which remain in some of their countenances, shew how narrowly they escaped the same premature destiny. The recollection of this dreadful malady will long survive in the traditionary songs of this simple people. The consternation which it excited is still as fresh in their minds as if it had been but an occurrence of yesterday, although the generation which witnessed its horrors, has almost past away. The moment one of them was seized with it, it was the signal for abandoning him to his fate. Brothers deserted their brothers, children their parents, and parents their children; and in some of the caves on the coast, heaps of decayed bones still indicate the spots where the helpless sufferers were left to expire, not so much perhaps from the violence of the disease as from the want of sustenance.

This fatal instance of the inveteracy of this disorder, when once introduced into the colony, has not been without its counterpoising benefit. It has induced the local government to adopt proper measures for avoiding the propagation of a similar contagion among the colonists. The vaccine matter was introduced with this view many years back; but as all the children in the colony were immediately inoculated, it was again lost from the want of a sufficient number of subjects to afford a supply of fresh virus; and for many years afterwards, every effort that was made for its re-introduction proved abortive. Through the indefatigable exertions, however, of Doctor Burke, of the Mauritius, the colonists are again in possession of this inestimable blessing; and there can be no doubt that proper precautions will be taken to prevent them from being again deprived of it.

The colony of New South Wales possesses every variety of soil, from the sandy heath, and the cold hungry clay, to the fertile loam and the deep vegetable mould. For the distance of five or six miles from the coast, the land is in general extremely barren, being a poor hungry sand, thickly studded with rocks. A few miserable stunted gums, and a dwarf underwood, are the richest productions of the best part of it; while the rest never gives birth to a tree at all, and is only covered with low flowering shrubs, whose infinite diversity, however, and extraordinary beauty, render this wild heath the most interesting part of the country for the botanist, and make even the less scientific beholder forget the nakedness and sterility of the scene.

Beyond this barren waste, which thus forms a girdle to the coast, the country suddenly begins to improve. The soil changes to a thin layer of vegetable mould, resting on a stratum of yellow clay, which is again supported by a deep bed of schistus. The trees of the forest are here of the most stately dimensions. Full sized gums and iron barks, along side of which the loftiest trees in this country would appear as pigmies, with the beefwood tree, or as it is generally termed, the forest oak, which is of much humbler growth, are the usual timber. The forest is extremely thick, but there is little or no underwood. A poor sour grass, which is too effectually sheltered from the rays of the sun, to be possessed of any nutritive and fattening properties, shoots up in the intervals. This description of country, with a few exceptions, however, which deserve not to be particularly noticed, forms another girdle of about ten miles in breadth: so that, generally speaking, the colony for about sixteen miles into the interior, may be said to possess a soil, which has naturally no claim to fertility, and will require all the skill and industry of its owners to render it even tolerably productive.

At this distance, however, the aspect of the country begins rapidly to improve.
