SUMMER IN SOUTH AMERICA. Summer was in its prime;- the parrot flocks
There, through the trunks, with moss and lichens white, Darkened the passing sunshine on the rocks;
The sunshine darts its interrupted light, The chrysomel and purple butterfly
And 'mid the cedar's darksome bough, illumes Amid the clear blue light are wandering by;
With instant touch, the lori's scarlet plumes. The humming-bird, along the myrtle bowers,
Just heard to trickle through a covert near, With twinkling wing, is spinning o'er the flowers;
And soothing, with perpetual lapse, the ear, The woodpecker is heard with busy bill,
A fount, like rain-drops, filtered through the stone, The mock-bird sings—and all beside is still.
And, bright as amber, on the shallows shone. And look! the cataract that bursts so high,
Intent his fairy pastime to pursue, As not to mar the deep tranquillity,
And gem-like, hovering o'er the violets blue, The tumult of its dashing fall suspends,
The humming-bird, here, its unceasing song And, stealing drop by drop, in mist descends;
Heedlessly murmured all the summer long; Through whose illumined spray, and sprinkling dews, And when the winter came, retired to rest, Shine to the adverse sun the broken rainbow hues,
And from the myrtles hung its trembling nest. Chequering, with partial shade, the beams of noon,
No sounds of a conflicting world were near; And arching the grey rock with wild festoon,
The noise of Ocean faintly met the ear, Here, its gay net-work, and fantastic twine,
That seemed, as sunk to rest the noontide blast, The purple cogul threads from pine to pine,
But dying sounds of passion that were past; And oft, as the fresh airs of morning breathe,
Or closing anthems, when, far off, expire Dips its long tendrils in the stream beneath.
The lessening echoes of the distant choir.-BOWLES.

All the other metallic minerals found in this and the trade is said to have been both profitable to the country are of small importance compared to this, either parties, and highly beneficial to the country. It is, in regard to the value of the produce, or the number of however, chiefly interesting, as showing how little was people whom it employs. Iron ores are found in nature then known of the real wealth of this country, as the in two very distinct positions,—either as veins intersect vessels bringing this ore from the south must have ing other rocks, or as beds alternating regularly with passed along the shores of Ayr, and up the Firth of certain strata.
