A lady writes: "I inquired in vain at the Centennial Exhibition in the Egyptian Department for the Papyrus, and in the Swedish School Room for the Linnaea borealis. Now I suppose both plants are there, only not in conspicuous positions, where I hope they will be placed. Also, I hope some one, or ones, who live near the Centennial Grounds will wreathe that beautiful likeness of Linnaeus in the Swedish School Room, with Laurel and the Linnaea borealis, which my Botany tells me is now in bloom. I will add what Mrs. Lincoln says: " Kalm, a pupil of Linnaeus, whose name is given to the Kalmia (American Laurel), spent three years in America, and returned to Europe laden with botanical treasures. The sight of the American plants brought by his pupil, many of of which were entirely new to him, is said to have produced such an effect upon Linnaeus, that, although lying ill of the gout, and unable to move, his spirits were re-kindled, and in the delight of his mind he forgot his bodily anguish, and recovered from his disease."
