Thou lingering star, with lessening ray,
That lovest to greet the early morn,
Again thou usherest in the day
My Mary from my soul was torn.
O Mary! dear departed shade!
Where is thy place of blissful rest?
See'st thou thy lover lowly laid?
Hear'st thou the groans that rend his breast?

That Burns should have expressed, in such rapid succession, the height of drunken revelry in Willie brewed a Peck o' Maut and in the ballad of The Whistle, and then the depth of despondent regret in the lines To Mary in Heaven, is highly characteristic of him. To have many moods belongs to the poetic nature, but no poet ever passed more rapidly than Burns from one pole of feeling to its very opposite. Such a poem as this last could not possibly have proceeded from any but the deepest and most genuine feeling. Once again, at the same season, three years later (1792), his thoughts went back to Highland Mary, and he poured forth his last sad wail for her in the simpler, not less touching song, beginning—

Ye banks, and braes, and streams around
The castle o' Montgomery!
Green be your woods, and fair your flowers,
Your waters never drumlie;
There simmer first unfauld her robes,
And there the langest tarry;
For there I took the last Fareweel
O' my sweet Highland Mary.

It would seem as though these retrospects were always accompanied by special despondency. For, at the very time he composed this latter song, he wrote thus to his faithful friend, Mrs. Dunlop:—

"Alas! who would wish for many years? What is it but to drag existence until our joys gradually expire, and leave us in a night of misery, like the gloom which blots out the stars, one by one from the face of heaven, and leaves us without a ray of comfort in the howling waste?"

To fits of hypochondria and deep dejection he had, as he himself tells us, been subject from his earliest manhood, and he attributes to overtoil in boyhood this tendency which was probably a part of his natural temperament. To a disposition like his, raptures, exaltations, agonies came as naturally as a uniform neutral-tinted existence to more phlegmatic spirits. But we may be sure that every cause of self-reproach which his past life had stored up in his memory tended to keep him more and more familiar with the lower pole in that fluctuating scale.

Besides these several poems which mark the variety of moods which swept over him during the summer and autumn of 1789, there was also a continual succession of songs on the anvil in preparation for Johnson's Museum. This work of song-making, begun during his second winter in Edinburgh, was carried on with little intermission during all the Ellisland period. The songs were on all kinds of subjects, and of all degrees of excellence, but hardly one, even the most trivial, was without some small touch which could have come from no hand but that of Burns. Sometimes they were old songs with a stanza or two added. Oftener an old chorus or single line was taken up, and made the hint out of which a new and original song was woven. At other times they were entirely original both in subject and in expression, though cast in the form of the ancient minstrelsy. Among so many and so rapidly succeeding efforts, it was only now and then, when a happier moment of inspiration was granted him, that there came forth one song of supreme excellence, perfect alike in conception and in expression. The consummate song of this summer, 1789, was John Anderson my Jo, John, just as Auld Lang Syne and The Silver Tassie had been those of the former year.

During the remainder of the year 1789 Burns seems to have continued more or less in the mood of mind indicated by the lines To Mary in Heaven. He was suffering from nervous derangement, and this, as usual with him, made him despondent. This is the way in which he writes to Mrs. Dunlop on the 13th December, 1789:—

"I am groaning under the miseries of a diseased nervous system—a system, the state of which is most conducive to our happiness, or the most productive of our misery. For now near three weeks I have been so ill with a nervous headache, that I have been obliged for a time to give up my Excise-books, being scarce able to lift my head, much less to ride once a week over ten muir parishes. What is man?..."

And then he goes on to moralize in a half-believing, half-doubting kind of way, on the probability of a life to come, and ends by speaking of or rather apostrophizing Jesus Christ in a strain which would seem to savour of Socinianism. This letter he calls "a distracted scrawl which the writer dare scarcely read." And yet it appears to have been deliberately copied with some amplification from an entry in his last year's commonplace book. Even the few passages from his correspondence already given are enough to show that there was in Burns's letter-writing something strained and artificial. But such discoveries as this seem to reveal an extent of effort, and even of artifice, which one would hardly otherwise have guessed at.
