248 RICHARD WARNER AS VIEWED BY KALM. BY BENJAMIN DAYDON JACKSON, R.N.O. (SWEDEN) J HON. Ph.D., ETC. PETER KALM (1716-1779) was one of Linnaeus's foremost pupils, "Studiosus primarius" was the epithet used by the Swedish naturalist of him ; he travelled at the expense of Baron S. C. Bjelke in Sweden, Finland and Russia. In 1747, upon Linnaeus's powerful initiative, Kalm was commissioned to embark on a journey to North America, which was com- pleted in 1751. Previous to his departure, he was nominated the first occupant of the new Chair of Economy in the University of Abo, Finland, and took up his duties soon after his return to Europe, discharging them until his death. On his way out he had to wait six months in England for a ship to Philadelphia, largely owing to the insecurity at sea due to the War of the Austrian Succession. During this enforced stay in our country, he not only acquired an excellent knowledge of English but travelled in the neighbourhood of London, to observe the farming appliances and customs, with the view of improving agricultural practice in Finland. He was most active in procuring seeds for Linnaeus at Uppsala and in cultivating a friendship with prominent cultivators, par- ticularly with Richard Warner (1711-1775), of Woodford, Essex, and Philip Miller (1691-1771), of the Apothecaries' garden at Chelsea. The extracts which are appended are translated from the letters which have been recently published in the 8th volume of the first section of the Linnean correspondence issued by the University of Uppsala with the help of the Swedish Govern- ment. Forty-one letters from him to his revered professor are printed in this volume but only one from Linnaeus. Kalm explained that he had sewn up Linnaeus's letters into a volume, and this probably perished in the terrible fire which devastated the town and University of Abo in 1827. Attention has been recently directed to a list of American seeds which Kalm drew up on his return home ; see Journ. Bot., lx. (1922), pp. 334-5. London, 24TH March, 1748.
