compared to the volume of the river. A brook upon 

 which the flannel mill stands also brings in some pollution. 

 Shrewsbury, population 26,967, about 40 miles by river 

 from Welshpool, the river being very tortuous between 

 the two towns. The Shrewsbury sewage is poured into 

 Severn by several sewers without treatment. The town 

 has a small supply of spring water, which is supplimen- 

 ted by a large supply from the Severn. 



Ironbridge, Coalbrookdale, Coalport and Jack- 

 field, a cluster of small manufacturing places, population 

 about 5,250, 20 miles by river below Shrewsbury. Iron- 

 bridge is situated on the side of a steep cliff, and with 

 the other places mentioned, drains irregularly into the 

 river. Lime kilns and blast furnaces are here, and pottery, 

 bricks, &c. are manufactured ; no public water supply. 

 Clinkers, &c. are tipped on river bank. 



Bridgnorth, population 5,350, 9 miles by river

 population 24,830. Its sewage irrigates 548 acres of land. 

 The effluent goes into the Stour. The Stour is greatly

 from tin plate works, and refuse from paper mills. The 

 iron has, no doubt, a purifying rather than a harmful 

 affect upon the water, acting as a precipitant. 



The pollution from the factories is soon deposited, and
