[Footnote 17: The original of this drawing, for which I am indebted to Councillor of Justice H. Rink, of Copenhagen, was painted by a German painter at Beigen, in 1654. The painting has the following inscription:-- Mit Ledern Schifflein auff dem Meer De groenleinder fein bein undt her Boen Thieren undt Bogelen haben see Ire tracht Das falte lands bon winter nacht ] [Footnote 18: The birch which grows here is the sweet-scented birch (_Betula odorata_, Bechst.), not the dwarf birch (_Betula nana_, L.), which is found as far north as Ice Fjord in Spitzbergen (78 degree 7' N.L.), though there it only rises a few inches above ground. ] [Footnote 19: According to Latkin, _Die Lena und ihr Flussgebiet_ (_Petermann's Mittheilungen_, 1879, p. 91). On the map which accompanies Engehardt's reproduction of Wrangel's _Journey_ (Berlin, 1839), the limit of trees at the Lena is placed at 71 deg. N.L. ] [Footnote 20: On the Kola Peninsula, and in the neighbourhood of the White Sea, as far as to Ural, the limit of trees consists of a species of pine (_Picea obovata_, Ledeb.), but farther east in Kamschatka again of birch.--Th. von Middendorff, _Reise in dem aeussersten Norden und Osten Sibiriens_, vol. iv. p. 582. ] [Footnote 21: An idea of the influence exerted by the immediate neighbourhood of a warm ocean-current in making the climate milder may be obtained from the following table of the mean temperatures of the different months at 1. Tromsoe (69 deg. 30' N.L.); 2. Fruholm, near North Cape (71 deg. 6' N.L.); 3. Vardoe (70 deg. 22' N.L.); 4. Enontekis and Karesuando, on the river Muonio, in the interior of Lapland (68 deg. 26' N.L.). Tromsoe Fruholm Vardoe Enontekis January........... -4.2 deg. -2.7 deg. -6.0 deg. -13.7 deg.
