Mr. William Chinalls, has been so modified as to be free from all 
the former objections urged against its utility, and has accordingly 
been introduced into general use in many of the most, extensive 
mines. 
A valuable instrument also invented by Mr. Chinalls, called the 
Shifting Cartridge, well deserves the attention of the mine agent, 
its object being to deliver any given quantity of gunpowder into a 
hole bored in a rock for the purpose of blasting it, without that loss 
and hazard which attend the ordinary method of -charging. 
From this report the enlightened members of the community 
will be enabled to appreciate the value and extent of the labours of 
this society, they will discover the grand objects of the institution, 
and be induced, it is hoped, to co-operate in extending its views ; 
by which the obscure art of mining will be improved, the health, 
comfort, and life of the laborious miner ensured, and the political 
resources and opulence of the county augmented.
