The travellers, ever On tho alert to avau them-

comprising the entire eastern side OF Lake Tsad.
The projected Git is to be hoped by this timc 40
complished) journey to Borgu is important in u
fourfold light. First, the exploration of this coun-
try is in itself interesting; secondly, Borgu forms
q link between tho basin of Lake Toad and that Of
the Nile, ana tho observations Of compstent ira
vellers extended thus for towards the sstern part
OF Africa would seem to promise important resutts;
thirdly, it is hoped that from Borgu aud undor the
protection Of its people, Wadai and the oelo-
brated Bahr 81 Ghazal will be accessible to the ira
vollers, who hitherto, during their s.sy at Kuka.

and has ia the kindest manner recommended them
to the chiefs OF that country.
DR., Barth estimates the distance ut q mouths

q. least three months.
After the eafe eturn Of tao travellers and their
successful exploration of the eastern portion OF
that remarkable basin Of Lake Tssi, they witt
direct all their energies to the south
Asregards this last stage Of their gigantic jour

Indian Ocean, WHOA is the most important rs wali

Barth believes, from mass oil information reepec.-
ing the intervening regions whon he has already
collected, that more southerly route ia tns
direction or Lake NyaSsi, will be much more prac-
tcable than straight line to Monbas, on bearing

specting the Nyassi line indicates many poworfut
kingdoms densely peopled, interseotei by nu ne
rivers, very fertile, AMI Astounding in forests.
Let US pause TO consider for moment the re-
suits already gained by the exertions of two ira
vellers who began their work without noise or
ption, and who consider Lake Tsad ouly as
the commencement OF their more important labors.

form q network which covers tho greater portion Of
Northern Africa. Nor would it be right to mea-
sure their Investigations by nero distances; for it
must be borne in mind that up to this time--except
within the countries in the vicinity of tho sea-
shore-the entire continent Of Africa, betweea
Tripoli and the Cape Colony, and between the
Nile and the lower course OF tho Kawara, does
not present single point tho position Of which
had been determined with any degree Of accuracy.

The positions Of Lyon, Dsnham. and Clapperton,

spect to the astronomical observations, Ba.th and
Oyerweg are well supplied with instruments, and

these observations save the latitude Of Tin Tellust)
have as yet been sent home; but DIR. Oyerweg in
formed me in his last letter that the whole Of his
astronomical, as well Us hypsometrical and moteo-
Iolog ical observations, will be sent TO Europe pre-
viously to their leaving Bornu. DR.. Overweg is
also the first geoogis who has visited those regions
Within only three four months after their arri-
val at Kuka the travellers had already successfully
nnvigated Lake Tsad, and penetrated $50 miles to
the south; while Denham, during his stey of seven
teen N onths OF that place, failed in accom- psninX
either of these desderata.
Next May or June. when the travellers intend
to depart from Lake Tsad TO tho south, they will
have devoted two years and half to their under
takirg and two years are considered ueces-
sary for accomplishing the second part Of their jour
ney. The funds at their command for this journey,
Of from four to five years, ere indeed very nade-
quate. Having now received the whole Of the sum
originally granted by the English government
consisting of few hundred pounds-and we'll nigh
exhausted their own private means, their chief re-
sources are G200, which to be at their disposal
only when reaching the shore Of the Indian ocean.
liz is to be lODeC that the generosity of tho Eng.
fish government will not let these brave follows
drop, and that some succor will be sent out coon
enough to reach them before their departure from
Lake Tad.
