The cobt of the 40 miles of Memphis sewerage was mider 

 £60,000, or less than one dollar and a-half per foot. The 

 various schemes for draining Memphis on the Combined System 

 were estimated to cost between £300,000 and £400.000. In 1889 

 I received a letter from Colonel Waring stating that the System 

 had been much improved, and was being applied to many differ- 

 ent places in America. In localities where the sewage has to be . 

 raised from a lower to a higher level, Mr. Isaac Shone's pneu- 

 matic ejectors would in most cases answer much better, and be a 

 great deal cheaper than pumpmg. Mr. Shone's system consists 

 in forcing the sewage by means of compressed air, from iron 

 tanks, termed ejectors. The height to which sewage or wa'er 

 can be lifted by this system is practically unlimited. The town 

 can be completely sewered on this principle, ejectors being 

 placed at certain cross streets to receive the sewage from a 

 number of houses, the sewage being forced into and along air- 

 tight mains to thn outfall. 1 had an opportunity of inspecting 

 this System in full work at Eastbourne in 1885, and was much 

 pleased with what I saw. In that town there were seven pneu- 

 matic ejectors, which were supplied with compressed air from 

 one station, one ejector being about two miles from the station. 

 The cost of working the system at Eastbourne — the sewage of 

 which was entirely, and the rainfall to a large extent, managed 

 by it, was £600 per annum ; the total cost of land, plant, houses, 

 etc., being £8,500. I'rom all that I have been able to learn, 

 the system has worked satisfactorily up to the present time. 

 The application of Shone's pneumatic ejectors to the small pipe 

 system of Colonel Waring, would, I am of opinion, form the 

 most perfect system of sewerage as well as the most economical, 

 not only in the first outlay but also in maintenance, that we 

 have any knowledge of at present. Where the sewage could be 

 dealt with by gravitation, the Separate System of Colonel Waring 

 would answer all requirements, and would, I believe, be much 

 cheaper, and possibly more reliable, than Shone's system ; Init 

 when it is necessary to raise the sewage from a lower to a higher 

 level, 1 am convinced that Shone's pneumatic ejectors are 

 superior to, and much cheaper than, pumping. Furthermore, 

 the number of ejectors that can be operated on from a central 

 station is practically unlimited. For a place such as Jh-isbane,
