It used, not very long ago, to be pretty generally believed by our southern brethren, that there were few trees in the Lowlands of Scotland, and none at all in the Highlands. They had an obscure notion that trees either could not or would not grow in such a soil and climate--cold and bleak enough at times and places, heaven knows--yet not altogether unproductive of diverse stately plants. They know better now; nor were we ever angry with their ignorance, which was nothing more than what was to be expected in persons living perpetually at home so far remote. They rejoice now to visit, and sojourn, and travel here among us, foreigners and a foreign land no more; and we rejoice to see and receive them not as strangers, but friends, and are proud to know they are well pleased to behold our habitation. They do us and our country justice now, and we have sometimes thought even more than justice; for they are lost in admiration of our cities--above all, of Edinburgh--and speak with such raptures of our scenery, that they would appear to prefer it even to their own. They are charmed with our bare green hills, with our shaggy brown mountains they are astonished, our lochs are their delight, our woods their wonder, and they hold up their hands and clap them at our cliffs. This is generous, for we are not blind to the fact of England being the most beautiful land on all the earth. What are our woods to hers! To hers, what are our single trees! We have no such glorious standards to show as her indomitable and everlasting oaks. She is all over sylvan--Scotland but here and there; look on England from any point in any place, and you see she is rich, from almost any point in any place in Scotland, and you feel that comparatively she is poor. Yet our Lowlands have long been beautifying themselves into a resemblance of hers; as for our Highlands, though many changes have been going on there too, and most we believe for good, they are in their great features, and in their spirit unalterable by art, stamped and inspired by enduring Nature. We have spoken, slightly, of the sylvan scenery of the Highlands. In Perthshire, especially, it is of rare and extraordinary beauty, and we are always glad to hear of Englishmen travelling up the Tay and the Earn. We desire that eyes familiar with all that is umbrageous should receive their first impressions of our Scottish trees at Duneira and Dunkeld. Nor will those impressions be weakened as they proceed towards Blair Athole. In that famous Pass they will feel the power possessed by the sweet wild monotony of the universal birch woods--broken but by grey crags in every shape--grotesque, fantastical, majestic, magnificent, and sublime--on the many-ridged mountains, that are loth to lose the green light of their beloved forests, retain it as long as they can, and on the masses of living lustre seem to look down with pride from their skies.
