IT IS TAKEN OUT TO SEA AND SCAT
 TERED OVER THE WAVES

 Method of Separating the sIndge from
 tho EGluent--cleau shipA
 ~Oh, how unpleasant The idea of go ing to sea with sludgeT On the con trary you know nothing of 1t. The deck of the sludge ship is broad and clean the deck house or saloon sma!l but comfortable. on the bridge q fresh breeze is blowing; the sunlight sparlles brightly on the ruilled surface of the river, and you scarce can realize that this fine steamer is carrying a thousand tous of London sludge out to sea. Yet such is the fact The idea that the mud barges' of the county council which take ont the precipitated portion of London sewage to the Barrow deep are simply dirty dredges is quite lnis take They are powerful twin screw steamships worked by two sets of triple expansion engines, and titted with three large tanks, kept covered, and abso lutely free from nuisance to anybody even to the seamen on board, They can make two trips out to sea in every twenty-five hours, steaming about ten knots, and as matter of fact. they thus dispose of 4l, ,000 tons of sludge in q week.
 The sludge is pret pitated by treat ing the sewage with lime and sulphate of iron First, six huge cages catch debris, such as sticks and dead rats and eels etc, in the great rushing sewers which drain London This rubbish Is burned in aestrnctors tt the rate of something hke hundred tons a week; then the black river of sewage is stirred in tanks with lime-ors moro correctly. lime water in the proportion of about 8b grams to the gallon. The effect oi the lime is to precipitate matter in sus pension and solution and also to deodor ize You may take smelling bottle with you if you like, but with plenty Of lime about you will hardly need t. But walking on along the top of the twenty. soyan feet wide sewer, which is probably to become beautiful boulevard for Barking. one comes to the sulphate of iron shop where a50 tons at time are received and where after being dis solved n the proper proportion as di racted by the chemist in charge, it, too fluids it's way to the swift river of sew age.
 But then comes 8 pause in the riyera mad career lt is almttoi through the i Penstock chamber that is, building with a number Of iron gates to a set oi covered precipitaung channels where t can IcisuraIy meditate after i;s wild rushings from London Here in is ! quiet bed the lime and iron in casting ! down the solid portions, eau take fqll | eaect, and the clear portion of the liquid ' at the top--pow called the eiiuent- | is let on over the hasl of d wall at the eid uf the chamber to channel It tlIq other side. whence gathering speed again, 1t rushes to reservoir, from which at cob tide it joins the Thames The siudso pgssos through pipes from ! the bottoms of the pgocipitaliug cham hers to another reservoir. whence t is pumped to the tanks in the sla0ge ! ships and conveyed to sea.
 The effect on the river is most satis, factory On the testimony of the har- 1 bor master it is cleaner HOW than it has i been for some years. while Mir Ihudi- chum, the chemist at the Barking ont fall works. joyfuIly maintains it has 30 per cent, Of oxygen, which t has not reloiced in for some summers past But 1 the cieau farash0re and the scent of sea weed ay Barking and the much parer i looking water iu tho Thaiaes itself, are proofs to the uniniUated of the success ot the new system
 That system IS only now getting into ] full working order The county coun- 1 cil have added two more ships 10 thg fleet, making now five in all. and iey ! are conveying some ,00O taus of slUdge 1 ont to sea every week, Four ships are constantly at work day and night, and one takes its turn of 8 rest week fol painting, repairs. etc., and aGorliag a lighter time for the men These arl sNlors and sleep on board regular watches being kcpt except one tweaty. foHr hours in every seven d.lya, wueA they are allowed or duty.
 The digchargng ground of thc steam. CTS s the Barrow deep, some miles be. youd the Eore light The deep is an unused channel Che north boand vessel. taking "a course considerably to the lefi and southward ship7 far 10 the right The channel has been baoycl by the council and no captain may commence dischargins until be has passed th( North Knot buoy The discharge i qpickly effected by opening valves in tho yessel's bottom, the principle being rrch the same as that used on the sell emptyiug lifeb0at--which, indeed, is bu an adaptation of tho law that water fnd its own level the bottom of the tank being built on level with the sea ThC valves are easily opened from the deck and SO quick is their action that tht whole thousand tons can be discharged in seven minutes. Generally the tim' occupied, however, is longer, the vesse perhaps steaming ten miles while empty ing her strange cargo The white wak' of the ship is discolored, gulls hove. over 1t, and then among the tumblinl waves and the fresh breezes tho sludgt is gone
 The mind can hardly grasp the fac that hundred million gallons of sewagl pour down the huge drain to Barking every twenty-four hours. But if VI think for q moment that this immens mass of sludge would, but for the ships have been discharged into the Thane between Grayesend and London bridge and be washing backward and forwar' with the tides. and that this would b always going on month after month, w may begin to have some conception o the benefit gained St. James Gazette
