I do not dare invite you earnestly to come to Concord, because I know too well that the berries are not thick in my fields, and we should have to take it out in viewing the landscape. But come, on every account, and we will see—one another.

No letters of the year 1851 have been found by me. On the 27th of December, 1850, Mr. Cabot wrote to say that the Boston Society of Natural History, of which he was secretary, had elected Thoreau a corresponding member, "with all the honores, privilegia, etc., ad gradum tuum pertinentia, without the formality of paying any entrance fee, or annual subscription. Your duties in return are to advance the interests of the Society by communications or otherwise, as shall seem good." This is believed to be the only learned body which honored itself by electing Thoreau. The immediate occasion of this election was the present, by Thoreau, to the Society, of a fine specimen of the American goshawk, caught or shot by Jacob Farmer, which Mr. Cabot acknowledged, December 18, 1849, saying: "It was first described by Wilson; lately Audubon has identified it with the European goshawk, thereby committing a very flagrant blunder. It is usually a very rare species with us. The European bird is used in hawking; and doubtless ours would be equally game. If Mr. Farmer skins him now, he will have to take second cut; for his skin is already off and stuffed,—his remains dissected, measured, and deposited in alcohol."

TO T. W. HIGGINSON (AT BOSTON).

Concord, April 2-3, 1852.

Dear Sir,—I do not see that I can refuse to read another lecture, but what makes me hesitate is the fear that I have not another available which will entertain a large audience, though I have thoughts to offer which I think will be quite as worthy of their attention. However, I will try; for the prospect of earning a few dollars is alluring. As far as I can foresee, my subject would be "Reality" rather transcendentally treated. It lies still in "Walden, or Life in the Woods." Since you are kind enough to undertake the arrangements, I will leave it to you to name an evening of next week, decide on the most suitable room, and advertise,—if this is not taking you too literally at your word.

If you still think it worth the while to attend to this, will you let me know as soon as may be what evening will be most convenient? I certainly do not feel prepared to offer myself as a lecturer to the Boston public, and hardly know whether more to dread a small audience or a large one. Nevertheless, I will repress this squeamishness, and propose no alteration in your arrangements. I shall be glad to accept your invitation to tea.

This lecture was given, says Colonel Higginson, "at the Mechanics' Apprentices Library in Boston, with the snow outside, and the young boys rustling their newspapers among the Alcotts and Blakes." Or, possibly, this remark may apply to a former lecture in the same year, which was that in which Thoreau first lectured habitually away from Concord. He commenced by accepting an invitation to speak at Leyden Hall, in Plymouth, where his friends the Watsons had organized Sunday services, that the Transcendentalists and Abolitionists might have a chance to be heard at a time when they were generally excluded from the popular "Lyceum courses" throughout New England. Mr. B. M. Watson says:—

"I have found two letters from Thoreau in answer to my invitation in 1852 to address our congregation at Leyden Hall on Sunday mornings,—an enterprise I undertook about that time. I find among the distinguished men who addressed us the names of Thoreau, Emerson, Ellery Channing, Alcott, Higginson, Remond, S. Johnson, F. J. Appleton, Edmund Quincy, Garrison, Phillips, J. P. Lesley, Shackford, W. F. Channing, N. H. Whiting, Adin Ballou, Abby K. Foster and her husband, J. T. Sargent, T. T. Stone, Jones Very, Wasson, Hurlbut, F. W. Holland, and Scherb; so you may depend we had some fun."

These letters were mere notes. The first, dated February 17, 1852, says: "I have not yet seen Mr. Channing, though I believe he is in town,—having decided to come to Plymouth myself,—but I will let him know that he is expected. Mr. Daniel Foster wishes me to say that he accepts your invitation, and that he would like to come Sunday after next. I will take the Saturday afternoon train. I shall be glad to get a winter view of Plymouth Harbor, and see where your garden lies under the snow."

The second letter follows:—
