For obvious reasons, the actual amount of tenders is 

 not given. It is not difficult to locate a works of this 

 character, and tenders are here treated as confidential 

 documents, concerning only those who send them and 

 those who receive them. For that reason, the cost of 

 foundations, engineering and supervision has been included 

 with the structures. The above summary shows that with 

 regard to gasholders, at all events, the pricing out of 

 quantities is done with great uniformity. 



Works No. 2. 



In the case of this works, the general constructional 

 details are similar to No. i, so that it is not proposed to 

 refer to them at length, except to point out important 

 differences. The land is 3 acres, 2 roods and 23 perches 

 in extent, near the railway, from which a siding has been 

 laid, and carried a little beyond the retort house. No doubt 

 some of this land will ultimately be disposed of, as it is 

 not likely to be required for gasworks purposes, even after 

 making a generous allowance for future possibilities. The 

 site is practically level, and of a clayey stratum. Included 

 in the site purchase is a stable, for which a rental of 10 

 per annum is received. 



The retort house is 68 feet by 30 feet wide. The roof is 

 formed of nine principals, at 6 feet 9 inch centres. The 

 rt-tort bench consists of three arches, two being com- 

 pleted with regenerative settings, seven and five retorts,
