One word now on another point. We must have a collector for plants living and dry to go to Santa Fé, with the Government Expedition. If I were not so tied up, I would go myself. Have you not some good fellow you can send? We could probably get him attached somehow so as to have the protection of the army, and if need be I could raise here two hundred dollars as an outfit. He could make it worth the while. He could collect sixty sets of five hundred plants (besides seeds and Cacti) very soon, which, named by us, would go off at once at ten dollars per hundred. Somebody must go into this unexplored field! Let me know if you think anything can be done, and I will set to work. The great thing is a proper man. July 15. I duly received your favor of June 25th; am delighted that you found a man to send to Santa Fé. I approve your mode of carrying out the plan, and will not be slow to aid in it. I wrote at once to Sullivant, telling him to forward fifty dollars for Fendler,[146]--to take his pay in Mosses and Hepaticæ, and to give instructions about collecting these, his great favorites. Before this reaches you, I am sure you will hear from him. He is a capital fellow, and Fendler must be taught to collect Mosses for him. Then came your letter of July 3d. All right. I immediately wrote to Marcy, the Secretary of War, and to Colonel Abert, the head of the Topographical Engineer Corps; asked for protection and transportation; told the secretary to send anything he might be disposed to do to you at St. Louis. I then inclosed your letter to Mr. Lowell, and have just received it back again, with his letter, which I inclose to you! Is it not handsome?... Now Fendler has money enough to begin with. As soon as he is in the field, and shown by his first collections that he is deserving, I can get as much more money advanced for him, from other parties. If he only makes as good and handsome specimens as Lindheimer, all will be well. His collections should commence when he crosses the Arkansas; his first envoi should be the plants between that and Santa Fé, and be sent this fall, with seeds, cacti, and bulbs, the former of every kind he can get. These must be confined to yourself, Mr. Lowell, and me, till we see what we get by raising them. Other live plants he had better not attempt now. His next collection must be at and around Santa Fé. But instruct him to get into high mountains, or as high as he can find, whenever he can. The mountains to the north of Santa Fé often rise to the snowline, and are perfectly full of new things. But you can best judge what instructions to give him. We can sell just as many sets of plants as he will make good specimens of. But forty sets is about as many as he ought to make.... It is said that a corps of troops is to be sent up through Texas towards New Spain. Lindheimer ought to go along, and so get high up into the country, where so much is new, and the plants have really “no Latin names.” October 8th.
