NOCTICES OF THE NORTHERN OR DUTCH HALF OF CELEBES. 
north. The longitudinal valleys are very few ; they are mostly trans¬ 
verse. There are therefore scarcely any plains : only three such are 
formed in the south by the strange concatenation of some side 
branches of mountains, viz., 1st. the plain of Gurontalo and Lim- 
botte, in length west to east 16 miles, and breadth 5 to 7 miles, which 
appears to have been originated by the retreating of the sea, being 
only a few feet above its level; 2nd, at Pagowat , and 3rd. near 
Moutton : both the latter are mere valleys. 
Of Plateaus only one is to be found, around the upper part of 
the river Pagogama, which is elevated about 300 feet above the level 
of the sea. 
The Rivers are numerous, but on account of the narrowness of 
the island, only a few are navigable for boats to a short distance. 
The rivers which flow into the bay of Tom ini are, 1st Gurontalo , 
being a discharge of water from the lake of Limbotte, flowing east¬ 
ward and then southward, receiving on its left the Bothair and Bo- 
langen, and attaining greater depth after being joined from the east, 
not far from the month, by the Boni. Small boats are able to ascend 
to the lake. 2nd. Pagogama, which runs from S.W. to S.E., has its 
sources upon and near Gulahatte, is narrow, deep cut, and with 
many rapids. Small boats go up as far as Tongabon. 3rd. Pagowat , 
from the north, very unimportant, is formed by the confluence of the 
Batu Duiango and Talo Duyuno. 4th. MUandao, running* south¬ 
ward, from Gunong Bamwah, is of a considerable breadth, and na¬ 
vigable far up ; it is very rich in gold, and not far from it are the 
mines of Wankahulu. 5th Malisipat, the most considerable of them 
all, runs southward, with many side-creeks, takes its rise from the 
mountains of Baol, and constitutes the frontier between Moutton 
and Gurontalo. 
Among the northerly streams deserve to be named: 1st. AndagUi 
from the mountain of Kasudipang, rich in gold, but otherwise in¬ 
considerable. 2nd. Quandam , from Gunong Pintu besar, having a 
very crooked course, and navigable for a short distance. 3rd. La- 
matta , from the slope of Gunong Marumi, with waterfalls and ra¬ 
pids. 4th. Sumalatte , having its sources on the Gulahatto; near it 
are the gold mines of Sumalette, 
Lakes inland.—The only one is in the plain of Limbotte, near the 
town of the same name ; lying from west, to east in length 4 miles ; 
and in breadth between Limbotte and Bolemo, 2 miles. 
Marshes .—There are some around the lake of Limbotte, some on
