the East of the old harbour ; it serves the Winter Gardens, 

 the Midland Hotel, and a small group of houses near this. 

 No. III., the " Queen Street " sewer, runs out obliquely 

 from Queen Street, near the Central Pier. Nos. IV. and 

 V., the " Calton Terrace " and " Thornton Road " sewers, 

 lie to the East of the Central Pier. No. VI., the " Bare 

 Sewer," is not shown on the chart; it serves the township 

 of Bare. Nos. II. to VI. deliver crude sewage, and Nos. 

 III. to VI. are 12-inch iron pipes. They all terminate at 

 low-water mark of ordinary tides. 



Taking a normal population of 11,000 and an average 

 water supply of 20 gallons per head per 24 hours, we find 

 that the main sewer outfall delivers 200,000 gallons of 

 purified sewage, and the other outfalls, 20,000 gallons of 

 crude sewage per 24 hours. 



Probably the contribution of the Old Harbour to the 

 pollution of Ping-Hole may be neglected. At the present 

 time the Harbour is strictly private ground, and is used 

 only for breaking up old warships and other superannuated 

 vessels. It is largely silted up, and though the bottom at 

 low water looks exceedingly foul, it is probable that this 

 foulness is more apparent than real. At any rate, the 

 only sewage matters issuing from it are those produced 

 by the workmen employed on the vessels. As a source of 

 pollution the Old Harbour does not count for much, and 

 whatever evil exists could easily be remedied. 



Sewers II. to VI. represent the outfalls of the 

 original Morecambe sewerage system before the new 

 scheme was brought into operation. For some years prior 

 to 1897 the Local Government Board had urged on the 

 Borough Council the desirability of adopting a system of 

 sewage purification. In 1897 they expressed the opinion 

 " that untreated sewage should not be discharged anywhere 

 in Morecambe Bay," an ideal which, except at Morecambe,
