land cannot be obtained, the proper way to treat sewage will be 

 to keep the effluent neutral and turn into it a charge of these 

 bacteria specially cultivated for the purpose ; and, after a sufficient 

 time has elapsed, pass a really purified effluent into the river. 



The sludf/e in the bottom of the tanks which, theoretically, 

 should be of great value, has, in practice, been a difficult thing 

 to deal with, and very seldom pays the cost of treating. In 

 most cases it has been allowed to lie on the ground to drain and 

 evaporate till it could be carted to the farm for manure ; in 

 others, baked to dry it more quickly, causing an abominable 

 stench ; it has been carted to sea ; burnt with ashes to make 

 clinkers for road making, and used in making cement, &c. 



During the last few years, however, sludge presses have come 

 into general use, the presses most used being Johnson's, Man- 

 love's and Drake's. The jprinciple of all these presses is that 

 the sludge is forced by direct action pumps or compressed air 

 into cavities at 60 to 100 lbs. pressure, and the liquid escapes 

 through strong cloth or cocoa-nut matting, leaving a solid cake 

 of sludge behind, easily handled, almost free from smell and not 

 liable to ferment. It is more valuable also as a manure than 

 when baked. 



Since the paper was read, the writer and the other members of 

 the Burnley Sewage Sub-Committee have visited several towns, 

 and decided on important alterations in the Burnley Sewage 

 Works, including the purchase of sixty-five acres of land for 

 filtration purposes, and the purchase of four of Johnson's presses 

 wliich are now being fixed for the treatment of the two million 

 gallons of sewage delivered at Duck-pits daily. 



BURNLEY STREET NAMES. 



By W. LEWIS GRANT, March 27th, 1888. 



After some observations upon Burnley in the early part of this 

 century, the reader observed that the word "gate" in Eastgate 

 (now Yorkshire Street) and Westgate meant " road." The paper 

 indicated the line followed by the old road which passed through 

 Burnley from West to East, prior to the days when the new 

 roads were constructed under the Blackburn, Addingham, and 

 Cocking End Trust. Modern methods have named the leading 

 roads diverging from the town after the places reached by them, 

 and some antique titles have accordingly been dismissed.
