March, 1900 
16 1003 "Salt water and gas, gas 
burned size of pipe 4 ft. 
high, stratum about 6 ft. 
thick." Mixed sample, part- 
ly light and partly dark gray 
color. Slight effervescence 
in cold HCl, which becomes Calciferous 
stronger on heating. sandrock 
17 1012 Light gray very tine grains, no 
effervescence in cold HCl, Calciferous 
but some on heating. sandrock 
18 1017 Very fine light gray to buff 
grains. No effervescence 
in cold HCl and scarcely 
any on heating; very silic- Calciferous 
ious sandstone. sandrock 
19 1020 Fine grains almost white like 
quartz. No effervescence in Calciferous 
either hot or cold HCl . sandrock 
20 1025 Very fine grains of light gray 
to slightly buff color. No 
effervescence in cold HCl, 
but a moderate amount on 
heating. Similar samples at Calciferous 
1030 ft. sandrock 
21 1035 Sample similar to above but 
composed largely of quartz 
grains. Ditto at 1040 and Calciferous 
1048 ft. sandrock 
22 1055 Quartz grains larger and a lit- 
tle more calcareous. Effer- 
vesces slightly in cold HCl. Calciferous 
Similar sample at 1060 ft. sandrock 
23 1070 Mostly grains of white Calciferous 
quartz. sandrock 
24 io<)5 Very fine light gray powder 
with some larger grains of 
quartz. Effervesces slightly Calciferous 
in cold HCl. sandrock 
25 1100 Light gray fine grains largely 
quartz, but some efferves- Calciferous 
cence in cold HCl. sandrock 
26 1 105 Fine quartz sand. Similar at 
1 108 ft. Probably top of the 
gneiss. Laurentian
