“to Lin Wasa, on the boundary of East Bothnia, forms the 
great Lake Estiri, flows through a great many other lakes 
connected with each other, sometimes by rapids, some- 
times by short connecting passages. Amongst these lakes 
may be mentioned the Toehwesi, the largest of the whole: it 
receives from the north-east the waters of the Keurunselka 
an l its tributaries; and at the point where the boundaries 
of Lakes Wasa, .\bo, and Twastehus meet, uniting with the 
Lake Ruowesi, and by several other lakes and connect- 
ing reaches of water, it pours its waters into the large and 
noble Lake Nosijeorivi, situated some 316 feet above the 
level of the sea; and this again empties itself into the 
Pyhajarivi, or Holy Lake, at the towo of Tammertors, by

Rautunselka, it pursues, its course through several 
torrents and small lakes, on the boundary between the 
Governments of Abo and of Tawasthus, till it reaches the 
southero extremity of Pyhajarivi. Out of this lake the 
waters collected thus from the north and from the south 
flow through the torrent Nokia into the Kulowesi,

in their courses form many waterfalls, amongst others, 
and well deserving notice, the waterfall of Kyro, or 
Kyronkosti. 
‘From the Kulowesi flows the mighty Kumostrom, 
which is strengthened by new affluents from the north 
and from the south, amongst others by the waters of
