From the widespreading roots string and ropes are manufactured in Lapland and Bothnia: the longer ones which run near the surface are selected, split through, and then boiled for some hours in a ley of wood-ashes and salt, which, dissolving out the resin, loosens the fibres and renders them easily separable, and ready for twisting into cordage.

- A line drawn from the head of the Gulf of Bothnia to the eastern coast of Lake Ladoga divides Finland into two distinct parts, the lake region and the nearly uninhabited hilly tracts belonging to the Kjolen mountains, to the plateau of the Kola peninsula, and to the slopes of the plateau which separates Finland proper from the White Sea.
Quite different is the character of the pentagonal space comprised between the Gulfs of Bothnia and Finland, Lake Ladoga, and the above-mentioned line traced through the lakes Ulea and Piellis.
A regular gentle slope leads from these hills to the Gulf of Bothnia (Osterbotten), forming vast prairie tracts in its lower parts.
The chief lakes are: Lake Ladoga, of which the northern half belongs to Finland; Saima (three and a half times larger than Lake Leman), whose outlet, the Vuoksen, flows into Lake Ladoga, forming the mighty Imatra rapids, while the lake itself is connected by means of a sluiced canal with the Gulf of Finland; the basins of Pyha-selka, Ori-vesi and Piellis-jarvi; Pajane, surrounded by hundreds of smaller lakes, and the waters of which are discharged into the lower gulf through the Kymmene river; Nasi-jarvi and Pyha-jarvi, whose outflow is the Kumo-elf, flowing into the Gulf of Bothnia; Ulea-trask, discharged by the Ulea into the same gulf; and Enare, belonging to the basin of the Arctic Ocean.
Two large rivers, Kemi and Tornea, enter the head of the Gulf of Bothnia, while the Ulea is now navigable throughout, owing to improvements in its channel.

The sk,rgard of the Gulf of Bothnia is less fully developed than that of either the Baltic or the Cattegat.
Between these extremes the following actual average temperatures have been observed at certain stations from north' to south which are appropriately grouped for the purpose of comparison (heights above sea-level following each name) Jockmock (850 ft.), at the foot of the lake-chain on the Little Lule River-29.7°; and Haparanda (30 ft.), at the head of the Gulf of Bothnia-32.4°.

At the time of the last great subsidence, in glacial times, an arm of the sea extended across Sweden, submerging a great part of the littoral up to the Gulf of Bothnia, and including the Plies period the this of themnorthe and Baltic were s fg ficiently salt for oysters to flourish.
At this time the Gulf of Bothnia must have suffered greater depression than the Baltic proper, for the deposits of that epoch show a thickness of 100 metres (328 ft.) near Hernosand, but of only 25 metres (82 ft.) in the neighbourhood of Gotland.
Sieger has traced a series of isobasic lines, or lines of equal rate of elevation, for portions of Sweden and Finland; these indicate that the movement is now almost nil along the axial lines of the Baltic and the Gulf of Finland, but increases in amplitude northwards to the Gulf of Bothnia and in the direction of the main ridge of the massif of southern Sweden.
