or capsules of their seeds, forming the most compact kind of 
rafts. Under this raft of the Red River, various small streams 
disappear, and shew themselves again after having passed seve- 
ral miles under the surface, and under sand banks, which are 
probably part of the raft buried under the sand.-— The rafts on 
the Achafalaya have been more recently examined by Mr Dar- 
by, who has given an account of them in his Emigrants Guide. 
He remarks, that men may pass the river in many places upon 
the wood. The timber, he says, rises and falls with the water, 
— -is continually shifting, — lies in all directions, having large in- 
terstices open,— -and frequently moves in a body from the weight 
of the incumbent mass. The raft is described by Mr Darby as 
only twenty miles long from its upper to its lower extremity, 
ten miles of which is completely closed with timber. — American

19. Rewards for Discoveries in the Arctic Regions. — In the 
New Longitude Act, which is the 58th of Geo. III. amended, 
it is assumed, that no ship has gone beyond 81° of North Lat.

which it proposes are : 
L. 5000 to any subject of Great Britain who shall reach the

Circle ; 
L. 10,000, besides the above, for the North-West Passage 
into the Pacific ; 
L. 1000 for reaching 83° of North Lat., and a similar sum 
for 85°, 87°, and 89°, respectively.

nations beyond Lattakoo which I visited,”” says Mr Campbell, 
u the first was the Tammaha nation, the chief town of which 
was Meribowhey, which lies near 200 miles to the NE. of New 
Lattakoo. They abound in cattle, and cultivate, to a conside- 
rable extent around their town, a species of millet, called Kaffer 
Corn. — The next country beyond the Tammaha is the Mashow 
country, the chief town of which is Mashow, not a day’s jour- 
ney beyond Meribowhey, containing about 12,000 inhabitants, 
who are much in the same state as at Lattakoo, and speak the 
same language.— About 100 miles beyond Mashow is Kurree-
