Such is a fair statement of certain advantages to be derived from the abolition of the penny stamp, and the substitution of the penny label. The advocates of the stamp-duty allege that, while the foregoing line of argument may be perfectly valid, something, on the contrary, is due to the advantage of having well-supported metropolitan newspapers as centres of intelligence. These newspapers, say some of their publishers, are put to vast expense for early news, foreign and domestic; such news they at present permit every one freely to copy; but, if a host of small country papers are to spring up, piracy of this kind will no longer be tolerated. As newspapers go pretty much on the principle of giving and taking in the way of intelligence, any tendency to prosecute on the ground of piracy would, in all probability, soon cure itself; and, therefore, we would not greatly rely on this as a reason for maintaining an exclusiveness in the business of newspaper publication. A more serious argument against the creation of a host of cheap local papers, is the probable dissemination of much petty scandal, and matter of a partially libellous or offensive character; at the least, much bad writing. Supposing, however, that there is a chance of literature being thus to a certain extent deteriorated, it will not do to oppose an improvement, if it be such, from fears of this nature. Should the matter treated of in small local papers be sometimes of an objectionable character, the public taste will surely go far towards its correction; and why should not each provincial town have an opportunity of educating writers up to the proper degree of literary accomplishment? It is undeniable, that small towns stand in pressing need of local channels for advertisements, and here, we think, is their strongest ground. How much more important, in a town of 5000 inhabitants, that the principal mercer should have his fresh arrival of goods advertised in a paper which circulates 500 copies in that town, than in some county-town journal which sends to it only some thirty or forty copies! A sale of growing crops must, in like manner, be much more effectually advertised in a paper which circulates largely in a small district, than in one which is diffused sparsely over a large one. All this, indeed, is amply proved by the tendency which has been shewn of late years, in Scotland at least, to set up unstamped monthly local papers containing advertisements, and by the comparative success which these journals have met with.
Among the arguments for such arrangements as would promote the sale of newspapers, we see little or no stress laid upon the educational, which to us appears as the very strongest of all. The interest felt in the occurrences of the passing day is one of the most vigorous of all intellectual appetences. Give a man ready access to a journal in which this taste can be gratified, and his intellectual progress is certain. The utterly uneducated, seeing the pleasure which his fellows derive from the paper, will desire to learn to read, that he may enjoy the like pleasure. The man just able to read will be drawn on to reflect and judge, and in time he will desire intellectual food from books also. The cheap newspaper thus becomes a most powerful instrument for nursing the popular mind; and, if we consider how essential it is, where there are free institutions, that the bulk of the people should be enlightened, we must see what a great public end is to be served by this simple means. A place in the apparatus is, we think, rightly claimed by the small local newspaper, as a kind of A B C, or first form, where the young and untutored mind may be entered by way of preparation for higher studies.
THE VEGETATION OF EUROPE.
The publication of the volume, the title of which appears below,[3] is to be regarded as additional evidence that the tendency of science in the present day is towards wider and more comprehensive generalisations. Many readers who may be more or less familiar with certain species or even families of plants, will hardly have prepared themselves for a view of the phytology of a quarter of the globe, such as is given in outline in the interesting work now before us. The subject is one that has been largely investigated within the past twenty years, as may be seen in the records of the British Association, in the transactions of learned societies, and in the writings of numerous observers on the continent. Attempt after attempt has been made to explain the causes of the variations and effects of climate, their influence on vegetation, the appearance of certain floras in localities where they might be least expected, and to separate the natural and regular from the accidental. Different countries have been examined and compared with each other, and many of the differences accounted for; and in Mr Henfrey's volume we have an acceptable résumé of these various researches.
It becomes necessary, first of all, to study the influences—whether general or special—which affect the distribution of vegetation; to inquire into those freaks or aberrations of nature which favour in one place the production of plants that will not grow in another, under apparently similar circumstances; and why similar plants are found in places widely separated. Oranges will ripen on one side the Alps, but not on the other; grapes scarcely come to perfection out of doors in England, while on the other side of the Channel they ripen by thousands of acres; and several fruits which fail in our northern counties, are grown without difficulty in Denmark in the open air. Investigation soon shewed that temperature alone, mere heat and cold, was insufficient to account for the phenomena; but that moisture and dryness, the prevalence of certain winds, the chemical and physical conditions of soil, and the constitution of the plants themselves, would have to be considered in a proper inquiry into the subject.
Here we must notice a fact which has proved of essential service in the study of botanical geography—namely, the discovery 'that there is some law presiding over the distribution of plants which causes the appearance of particular species arbitrarily—if we may so say it—in particular places;' from which, the conclusion has been arrived at, 'that countries have become populated with plants partly by the spreading of some special kinds from centres within those countries where they were originally exclusively created; and while these have spread outward into the neighbouring regions, colonists from like centres lying in the surrounding countries have invaded and become intermingled with the indigenous inhabitants.'
Looking at the effect of climate on vegetation, we find that as we proceed from the north towards the south, the number and luxuriance of plants increase in a remarkable degree, and the same result is observable in altitude as in latitude. 'Step by step,' writes Mr Henfrey, 'as the land rises in any mountain region, the vegetation assumes, more and more, a polar character; and in the mountains of the tropics, a succession of stages has been distinguished, corresponding in the general peculiarities of the plants which clothe them, to tracts extending horizontally, in succession, on the sea-level, from the base of these mountains to the frozen regions within the arctic and antarctic circles. Increase of elevation is accompanied by an alteration of climate, bringing with it a set of conditions analogous to those prevailing at certain distances further from the sun. Ascending the Peak of Teneriffe, a series of regions are traversed, one above another, displaying with the approach to the summit a continually closer approximation in character to the polar regions, till the traveller who left the palm, the cactus, and the thousand varied forms of tropical vegetation at the foot, finds himself at last among the stunted shrubs and scaly lichens, the borderers who hold the outposts on the limits of the eternal snow.'
It might be expected that places on the same parallel of latitude would be equal in temperature; but on tracing out the distribution of heat over the globe, and laying it down in what are called isothermal lines on a map, most striking deviations are found to exist, and the contour of the lines is anything but regular. The line of greatest cold, for example, which leaves the eastern coast of Labrador at about the 54th degree of latitude, rises six degrees as it approaches Greenland, and strikes the coast of Lapland a little above the 70th degree, or sixteen degrees nearer the pole than at its starting-point—thus shewing that the northern parts of Europe have a more genial climate than those of America. The line then curves fifteen degrees to the south across Siberia, rises again on the western coast of America, and falls once more as it advances towards the east. Again, 'the isotherms of Canada pass through Iceland, across about the middle of Norway and Sweden, St Petersburg and Kamtschatka. Those of New York through the north of Ireland and England, twelve degrees further north, North and Central Germany, and the Crimea. That which leaves the United States at about 36 degrees north latitude, crosses Southern Europe from the north of Spain to the Adriatic in a tolerably straight line, some eight degrees further north, and then falls south again, where the influence of the north-east polar current is more felt, in Greece and Turkey.'
