In his earlier years the poet seems to have scattered songs as thick as a summer eve scatters its dews; nor did he scatter them less carelessly: he appears, indeed, to have thought much less of them than of his poems: the sweet song of Mary Morison, and others not at all inferior, lay unregarded among his papers till accident called them out to shine and be admired. Many of these brief but happy compositions, sometimes with his name, and oftener without, he threw in dozens at a time into Johnson, where they were noticed only by the captious Ritson: but now a work of higher pretence claimed a share in his skill: in September, 1792, he was requested by George Thomson to render, for his national collection, the poetry worthy of the muses of the north, and to take compassion on many choice airs, which had waited for a poet like the author of the Cotter's Saturday Night, to wed them to immortal verse. To engage in such an undertaking, Burns required small persuasion, and while Thomson asked for strains delicate and polished, the poet characteristically stipulated that his contributions were to be without remuneration, and the language seasoned with a sprinkling of the Scottish dialect. As his heart was much in the matter, he began to pour out verse with a readiness and talent unknown in the history of song: his engagement with Thomson, and his esteem for Johnson, gave birth to a series of songs as brilliant as varied, and as naturally easy as they were gracefully original. In looking over those very dissimilar collections it is not difficult to discover that the songs which he wrote for the more stately work, while they are more polished and elegant than those which he contributed to the less pretending one, are at the same time less happy in their humour and less simple in their pathos. "What pleases _me_ as simple and naive," says Burns to Thomson, "disgusts _you_ as ludicrous and low. For this reason 'Fye, gie me my coggie, sirs,' 'Fye, let us a' to the bridal,' with several others of that cast, are to me highly pleasing, while 'Saw ye my Father' delights me with its descriptive simple pathos:" we read in these words the reasons of the difference between the lyrics of the two collections.
