Charles Wright, who was in the North Pacific Expedition under Ringgold and Rogers, has left his ship at California instead of making the voyage round Cape Horn, and crossed over the Nicaragua route, intending to botanize there some months. Finding himself there among our vile filibustering people, and all in confusion, however, he was soon obliged to come on home. He is awaiting the arrival of his ship, and will not till this autumn be able to touch his Pacific collections, of which the best and principal were made in Hongkong, Bonin, and the Loo Choo Islands and Japan. That they are not larger is not his fault. Wright has a perfect passion for collecting plants; and already begins to plan other explorations. To satisfy his cravings for a while, I have proposed to him to go to St. Iago de Cuba, and explore that end of the island. What do you think of it? Has any botanist collected there? Would it be too like Jamaica to offer much novelty? But to return. In Nicaragua, Wright collected a goodly quantity of seeds, one set of which he wishes me to send to you; a present to Kew Gardens, as I understand it.... By the way, it was most lucky that I hurried up and had sent on to you the copy of Brackenridge’s “Filices;” for a fire in Philadelphia has consumed all of the poor fellow’s edition of the volume except ten copies which had been sold mostly in Europe. A sad and a heavy loss to B., who had no insurance, and something to me who had advanced to him the paper for printing it on, which now the poor fellow is in no condition to pay for. I have not even a copy of the atlas myself, but I shall get one from the government plates, which are preserved. Brackenridge utterly despairs of reprinting it. But possibly the government will set up the type for him again, as they have also lost a part of their small impression. Otherwise the book will have the value of excessive rarity, if it has no other.... May 25, 1857.
