My great object for next year is to attempt to raise $10,000 from some of our rich men, to rebuild our greenhouse on a larger and handsome scale. There are a few men, who have never given anything to the college, who may perhaps be induced to give for this object. TO GEORGE ENGELMANN. CAMBRIDGE, MASS., February 13, 1843. I note with interest what you propose in regard to Lindheimer’s collections for sale in Centuriæ, fall into your plans, and will advertise in “Silliman’s Journal” (and in “London Journal of Botany”) when all is arranged. Pray let him get roots and seeds for me. I will do all I can for him. But if the Oregon bill passes, a party under Lieutenant Frémont, or some one else, will go through the Rocky Mountains to Oregon; and parties of emigrants or explorers will go also. Now why not send Lindheimer in some of these? Probably the government party would afford him protection, and probably he might be formally attached to the party. Frémont will not take Geyer;[131] but I believe he wants some one. The interesting region (the most so in the world) is the high Rocky Mountains about the sources of the Platte, and thence south. I will warrant ten dollars per hundred for every decent specimen. If he collects in Texas, eight dollars per hundred is enough. I write in haste, hoping this plan may strike you favorably and be found practicable. Let me know at once. The opportunity should not be lost. Do send Lindheimer to the Rocky Mountains if possible. TO W. J. HOOKER. CAMBRIDGE, February 28, 1843. I found your most welcome letter on my return from New York a few weeks since, and have since sent it to Dr. Torrey, who was equally delighted with myself at the opportunity of hearing from you. Our term opens to-day, and I am just on the point of commencing my course of botanical lectures, which is rather formidable to a beginner. So you will excuse my hasty letter. I would not miss to-morrow’s steamer, as I wish to say that your offer to furnish our Garden--the great object of my care--with hardy plants from your rich stores at Kew delights me much. I have only to say that everything you can send will be truly welcome. Our stock of European hardy plants (whether herbs or shrubs) is small, and consists of the commonest and oldest-fashioned things in cultivation. These, and every Californian, Oregon, and Texan plant of which you have duplicates to spare us (or seeds), whether hardy or not,--these are the plants I am just now most desirous to accumulate. Greenhouse plants are scarcely less welcome, but of those I will write more particularly hereafter. Can you send us a young Araucaria imbricata and Stuartia pentagyna?
