Some time in 1860, Mr. Burroughs began to send essays to the New York "Leader," a weekly paper, the organ of Tammany Hall at that time. His first article was made up of three short essays—"World Growth," "New Ideas," and "Theory and Practice." Here beyond question is the writer we know:

The ideas that indicate the approach of a new era in history come like bluebirds in the spring, if you have ever noticed how that is. The bird at first seems a mere wandering voice in the air; you hear its carol on some bright morning in March, but are uncertain of its course or origin; it seems to come from some source you cannot divine; it falls like a drop of rain when no cloud is visible; you look and listen, but to no purpose. The weather changes, and it is not till a number of days that you hear the note again, or, maybe, see the bird darting from a stake in the fence, or flitting from one mullein-stalk to another. Its notes now become daily more frequent; the birds multiply; they sing less in the air and more when at rest; and their music is louder and more continuous, but less sweet and plaintive. Their boldness increases and soon you see them flitting with a saucy and inquiring air about barns and outbuildings, peeping into dove-cota and stable windows, and prospecting for a place to nest. They wage war against robins, pick quarrels with swallows, and would forcibly appropriate their mud houses, seeming to doubt the right of every other bird to exist but themselves. But soon, as the season advances, domestic instincts predominate; they subside quietly into their natural places, and become peaceful members of the family of birds.

So the thoughts that indicate the approach of a new era in history at first seem to be mere disembodied, impersonal voices somewhere in the air; sweet and plaintive, half-sung and half-cried by some obscure and unknown poet. We know not whence they come, nor whither they tend. It is not a matter of sight or experience. They do not attach themselves to any person or place, and their longitude and latitude cannot be computed. But presently they become individualized and centre in some Erasmus, or obscure thinker, and from a voice in the air, become a living force on the earth. They multiply and seem contagious, and assume a thousand new forms. They grow quarrelsome and demonstrative, impudent and conceited, crowd themselves in where they have no right, and would fain demolish or appropriate every institution and appointment of society. But after a time they settle into their proper relations, incorporate themselves in the world, and become new sources of power and progress in history.

This quotation is especially significant, as it shows the writer's already keen observation of the birds, and his cleverness in appropriating these facts of nature to his philosophical purpose. How neatly it is done! Readers of "Wake-Robin" will recognize a part of it in the matchless description of the bluebird which is found in the initial essay of that book.

In 1860, in the "Leader," there also appeared a long essay by Mr. Burroughs, "On Indirections." This has the most unity and flow of thought of any thus far. It is so good I should like to quote it all. Here are the opening paragraphs:—

The South American Indian who discovered the silver mines of Potosi by the turning up of a bush at the roots, which he had caught hold of to aid his ascent while pursuing a deer up a steep hill, represents very well how far intention and will are concerned in the grand results that flow from men's lives. Every schoolboy knows that many of the most valuable discoveries in science and art were accidental, or a kind of necessity, and sprang from causes that had no place in the forethought of the discoverer. The ostrich lays its eggs in the sand, and the sun hatches them; so man puts forth an effort and higher powers second him, and he finds himself the source of events that he had never conceived or meditated. Things are so intimately connected and so interdependent, the near and the remote are so closely related, and all parts of the universe are so mutually sympathetic, that it is impossible to tell what momentous secrets may lurk under the most trifling facts, or what grand and beautiful results may be attained through low and unimportant means. It seems that Nature delights in surprise, and in underlying our careless existences with plans that are evermore to disclose themselves to us and stimulate us to new enterprise and research. The simplest act of life may discover a chain of cause and effect that binds together the most remote parts of the system. We are often nearest to truth in some unexpected moment, and may stumble upon that while in a careless mood which has eluded our most vigilant and untiring efforts. Men have seen deepest and farthest when they opened their eyes without any special aim, and a word or two carelessly dropped by a companion has revealed to me a truth that weeks of study had failed to compass....

Nature will not be come at directly, but indirectly; all her ways are retiring and elusive, and she is more apt to reveal herself to her quiet, unobtrusive lover, than to her formal, ceremonious suitor. A man who goes out to admire the sunset, or to catch the spirit of field and grove, will very likely come back disappointed. A bird seldom sings when watched, and Nature is no coquette, and will not ogle and attitudinize when stared at. The farmer and traveler drink deepest of this cup, because it is always a surprise and comes without forethought or preparation. No insulation or entanglement takes place, and the soothing, medicinal influence of the fields and the wood takes possession of us as quietly as a dream, and before we know it we are living the life of the grass and the trees.

How unconsciously here he describes his own intercourse with Nature! And what an unusual production for a youth of twenty-three of such meagre educational advantages!

In 1862, in an essay on "Some of the Ways of Power," which appeared in the "Leader," he celebrated the beauty and completeness of nature's inexorable laws:—

There is an evident earnestness and seriousness in the meaning of things, and the laws that traverse nature and our own being are as fixed and inexorable, though, maybe, less instantaneous and immediate in their operation, as the principle of gravitation, and are as little disposed to pardon the violator or adjourn the day of adjudication.
