COAL-MEASUEES IN THE SOUTH-EAST OF ENGLAND. 243 
The Committee wisely contemplate the possibility of having to 
goto a depth of 1,500 to 2,000 feet, and will, we trust, take secure 
steps against such a contingency. At the same time we hope 
(and it is perfectly possible) that before they reach half that 
depth, the very interesting object of which they are in search 
may meet its solution, and that one more positive fact may 
be acquired to science in addition to those so fortunately fur- 
nished by the trial works at Kentish Town and Harwich.
