A fourth boring, 
In progress. 
Position. 
in the Ville N’oire, is still in operation, but as j'et there is 
no definite information as to a .satisfactory sheet of 
rising water having been tapped. 
The locality has been chosen on comparatively high ground ; but, from tho 
section, 1 fear it is altogether too near the Red Hills to 
gi^•e much hope of a suffieient supply of water being found 
in the proper alluvial deposits, though the news of a rising sheet of water i.s 
hopeful. The boring is abovrt 800 or 900 yards from the sea, and nearly 1.250 
yards north of the parallel of tho Savana well; it is also about 350 yards south 
of a largo back-watei' immediately north of the city. 
The inner diameter of the tube is 8'4 inches, but now that a depth of 550 
feet has been reached, it is proposed to insert a second 
tube of G’4 inches in diameter. 
The following sectional table (4) is translated from a copy of the books kept 
The boring section so ^t the boring, and 1 have in it again—though there is hero 
far. no such very decided grouping of the arenaceous and 
clayey strata as in the southern wells—attempted a classification of the bods ;—
