CELEBES 
281 
miles north of Makassar, after a course of about 200 
miles. The Bahu Solo, which rises in the Tafuti Lake 
and debouches just north of Nipanipa Bay in the south¬ 
eastern peninsula, is hardly more than 120 miles in 
length. Neither of these are navigable for anything but 
small craft. The Chinrana, however, which runs into 
the Gulf of Boni close to the town of that name, admits 
large native vessels for a distance of 50 miles or more. 
Celebes has few of the temporary lakes which are so 
marked a characteristic of the Philippine Islands and 
Borneo. It exhibits none of the vast level stretches of 
low-lying post-Tertiary land which are daily flooded by 
tidal action as in the latter country. But it has several 
fresh-water reservoirs, which are in some cases of con¬ 
siderable extent, though not, apparently, of great depth. 
The largest of these is Lake Poso, in the centre of the 
island. Lake Tempe is drained by the Chinrana, and is 
about 20 miles in length. Two other sheets of water, 
Tafuti and Eanu, each not less than 10 miles long, are 
situated near the head of the Tomaiki or Tolo Gulf. All 
these are little known, but the Limbotto and Tondano 
lakes are in districts long settled, and have Europeans 
living on their shores. The former is close to Gorontalo, 
in a plain surrounded by mountains, and was doubtless 
formerly of much larger area. Now it does not exceed 
7 miles in length. It is drained by the Gorontalo 
Eiver, which has carved its way to the sea through the 
coast-range by a short but steep gorge. The Tondano 
Lake, which is of much the same size, lies in the midst of 
some of the most beautiful scenery in the archipelago, 
the centre of the fertile and thickly populated district of 
Minahasa. It has been described as occupying the crater 
of an ancient volcano, but upon what grounds it would 
be difficult to say, for there is nothing to support such a
