tare run into I in the Gardens. 
Five rising sheets of water were tapped in the Garden well. The first rise

rate layers. 
During the whole time the boring was going on through the groups D, E, F, 
A steady rise through- ^ appears to have been a steady rise of 
out two thick hands of water until the 1st girsh was reached, even with the 
intervening (ordinarily impermeable) 37 feet of black 
clays of F, and the 48J feet of thick black clays of I. It is very difficult to account 
for this apparent permeability of such beds, even though the boring was carried 
on at an average rate of more than 3 feet a day. It may have been that the 
partings betu'cen the separate beds of clay in each group allowed of water 
percolating from thinned out beds of sand : indeed if my correlation of the 
lower group of clay beds with the separated clay beds in the Savana section 
be right, then the intermediate sand beds of the latter section would thin out 
between the thickening clays of the F group in this boring. This closing up 
of the water sheets also accounts for there being no such rises of water level as 
those which W'cre experienced in the Savana boring until the gi’oup H was 
passed. 
The 1st gush of water (in the Garden) took place in the group K at 185-32

remained until the sands of the middle of M were i-eached, wffien there was a 
2nd gush, which, however, fell to 12 inches below surface in the same beds. 
A 3rd gush took place in the fine sands of N, but this water soon fell to level 
of ground. At last in the ferruginous bods of O, the 4th and pennanent gush 
was reached.

Table (3), which bed does not appear to differ from 50 or 51 except in the 
absence of small clots of clay. It may bo that these clots of clay are so matted 
together as to have formed a temporary inipernioahlo layer. They are present in 
the bottom layers of N, from under which the 8rd gush arose, while the 1st gush 
came from slightly claj-ey hods. It seems to me that it can hardly be said that 
these gnshes, vi%., the 1st 2nd, 3rd, and 4th, are really from different water 
sheets; hnt rather that they, like the lower ones in the Savana well, are from 
an irregularly permeated thickne.s.s of sands and some clays which required time 
for free circulation to he brought about. Thus, I would suggest that both the 
Savana and the Garden well do after all gather their waters from the same 
group of sandstones.
