Cambridge, August 6, 1861.

My dear Engelmann,—As soon as I got clear of college work, my wife and I started off (on the 12th of July) to visit my mother and friends in Oneida County, New York, where we rode and drove about in the fine air, over a most beautiful country, and enjoyed ourselves to the full, to her great advantage; also mine. Then we cut across the State to Pennsylvania, visited the coal region of north Pennsylvania; traveled very leisurely; passed through New York, seeing the Torreys three hours, and so to Litchfield, Connecticut, where Mrs. G. is left, and I am at home, to set to work again, having done nothing in botany except to teach since last April.

Now I am going to set to work as soon as correspondence is cleared off.

I found here also a letter from Dr. Parry,[48] and have named the specimens in both, sending the answer to you for forwarding, also Dr. Parry’s letter to me.

He can’t miss it if he keeps at work between Denver and Salt Lake, climbing to truly alpine regions as often as he can.

Dr. Hooker sent me last spring a fine cast of a bust of Robert Brown. To-day I have also from him a splendid one of his father, Sir William. Tell Fendler that Mr. Shaw should procure both if possible for the Library of Hort. Bot., Missouri.

What next? A young gardener has found a locality of Calluna vulgaris, covering almost an acre, within twenty-five miles of Boston; a case to add to Scolopendrium, Marsilea, etc., but most of all, striking and unexpected. It grows in low ground, and has every appearance of being indigenous.

I hope and trust that Frémont will be strong enough to keep the war out of your neighborhood. The citizens of Missouri ought to volunteer in such numbers as to keep the rebels out of the State and keep the State true and firm in the Union. It is the cheapest and most honorable way, and will save property, avoid distress, etc.

This rebellion is certainly going to be put down, no matter at what cost, and property at St. Louis will be worth more than ever yet before you and I reach three score and ten.
