Note 40 — PART IX.
Reading edition
Mr. Lee of Manchester supplies his house, two miles distance from the manufactory, by means of a portable gas holder.[41] A small carriage upon springs conveys two square close gas holders made of wrought iron plates, and each containing fifty cubic feet of perfectly purified gas, equivalent together to about six pounds of tallow. Each gas holder weighs about 160 pounds; and has a valve at the bottom, which is opened by the upright main pipe, the moment the gas holder is immersed in the pit. The strength of one man is found sufficient for the labour of removing the gas holder from the carriage to its place.
