Red Sulphur Springs, Virginia. August, 1855.

My Dear "Horticulturist." - I little expected when our fortunes were linked together some few weeks ago, that I so soon should have found myself five hundred miles away from your new home, but the medical advisers decided for me, and after preparing nearly as much mental pabulum for you as your appetite seemed to require, I find myself drinking the "Red Sulphur Water" in this delightful mountain region, and feel disposed to have a little chat with you. Your own example of roaming from place to place might excuse my doing likewise, for to tell you a home truth, you have been a little unsettled in your residence yourself I Your education begun on the North River under an able master; it was completed by taking a full " pomological" course at Rochester, and now you have come to Philadelphia to see what can be learned there. I will not conceal from you that there are differences of opinion respecting your career, and that some of your admirers even think you have been a little too " pomological," but you are prepared, I know, to meet these differences, and will, probably, like all wilful youths, take your own course after all.

But do you know there are others who would fain hybridise you ? It is true; I brought with me a letter or two positively advising this; they would make a compound of you between a monthly magazine, a newspaper, and a Horticulturist. They wish you, my dear H. to contain matter like Putnam and Harper, and an abstract of the news of the month! What think you of that? Will you cheerfully yield your already crowded space to lengthy biographies, such as Abbott's Napoleon ? And would it be agreeable to your habits of mind to retail the entire history of the Kinney expedition, and the controversies about Neil Dow, and the liquor question in general ? Would you after so much preparation like to "know nothing ?" Have your previous studies qualified you for this ? Or would your fastidious taste put up with it? I know what your private opinion is about all this, and perhaps it will be better for your health if I drop the subject.

But touching these removals from place to place, you believe, I know, that the climate of Philadelphia is agreeing with you, and think it likely to be a pleasanter winter, and a more permanent residence than Rochester, because you can delight in your out-door occupations later in the fall and earlier in the spring; though your duty is to tell all about pinching the dwarf pears, you see no reason why your own nose should be pinched off every winter in the hyperborean climate so near to Canada as your late residence. This is all very well, and I am rejoiced, for you that you have moved into a warmer atmosphere, and among a people that are inclined to make much of you.

But I must ask you a serious question; are you so fond of " moving " that you must repeat the operation ? If so, and the habit is a confirmed one, which I am happy to think is not however the case, let me give you a little advice. I am not entirely convinced that a "move" now and then, such as you have already made, might not be wholesome and useful, so that if your medical advisers should ever again recommend such a step, which I believe their good sense will prevent them from doing, I will tell you at once how I think it would be prudent to proceed. By wandering occasionally to new scenes, you may very probably pick up knowledge and information that will tend to your usefulness as a public teacher; you can ascertain all that is known in each city where you reside, and gain an amount of sound education that will make you a phenomenon of the first water in your older age.

I think it might be advisable that you should live a year sometime in Boston. Those eastern sages know a great deal, and they are learning every day something to advance your favorite studies; they are practical people, these Boston and Roxbury cultivators ; they will treat you well and give you plenty of pears and apples, however they may be inclined to deny you perry and cider.

Whether six months or a year's residence in the city of New York would form an agreeable or useful variety in your career, I am not now prepared to decide. That city has many enthusiastic lovers of horticulture, who are also your friends, and I have not the least doubt they would give you a warm welcome. Your readers are rapidly increasing there, so that arrangements have been perfected to report more particularly than heretofore, their "sayings and doings".

I think you would perhaps do well after leaving Boston to cross the mountains, give Pittsburg and Cincinnati the benefit of your experience, learn all they know about the raising of grapes and the manufacture of wine, all about the great question of strawberries; and while you are on this excursion it would be proper to tarry a suitable time in Louisville and St. Louis. There is much to interest there.

I now come to the most serious part of your journeyings. I want you, if you must ramble, to pass a year at least in California, Oregon, and Washington territory! .Don't be alarmed at the journey. It will soon be a safe one, such as you can conveniently make with your " types" about you, though if your issue is regular, you might have to print one number on a stump on the route, or, say at Mormondom, where they have done but little for any good cause as yet. One number at least I want issued from the grove of big trees!! They say the "discoverer" and "describer" of a tree or plant has a right to name it! But you may turn the tables on that Lobb-ying fellow, and take the right upon yourself as the first printer under their branches, and as soon a* you do this, I know you will change the name to Washingtonia, and we will support you in it, be assured!

While in California I want you to make popular descriptions of all their desirable trees and other productions, and tell us what we shall adopt in our eastern plantations. Oregon and Washington, too, require more delineations in your line, and you will doubtless pick up many valuable plants and trees on your journeys there and back that have never been popularised. Now all this looks truly formidable to you, does it not ? If so, let us see whether we cannot jog on together in Philadelphia, and accomplish all this great work by means of our numerous correspondents.
