8. It is proposed to utilize the furnaces and provision must be made accordingly-
(a.) To cremate carcases of cattle (this will only be necessary occasionally). (b) To cremate, or dry for manure, offal from the Slaughter-Houses.
(c.) To destroy mattresses and infected clothing.
(d.) To supply heat for a 100-11. P. boiler.
Note.-It is proposed to use this boiler to supply steun for the following purposes, which
are stated for guidance and not for an estimate.
(i.) For heating water for use in the Slaughter-Houses.
(ii.) For a disinfecting plant.
(iii.) For driving an engine of 50-H, P.
9. In submitting the plans and tender the following particulars should be given :---
(a.) The quantity of refuse which will be guaranteed to be burnt per furnace per diem. (6.) The total H.-P. which it is estimated can be obtained from the furnaces.
(c.) The type of boiler which it is proposed to fix. A price should, however, be quoted for both a Lancashire and a Water-tube boiler though it does not follow that either of them will be adopted.
(d.) The proposed height of chimney. It must be remembered in designing the chimney that it will probably be close to the Slaughter Houses and that no dust must escape. (e.) The estimated annual cost of repairs per furnace.
10. The estimated cost of the works should be given in detail under the following headings :-
(a.) Cost of furnaces and flues.
(b.) Cost of chimney.
(c.) Cost of destructor buildings.
(d.) Cost of boilers.
(e.) Freight of special firebricks, boilers, iron-work, &c., to Hongkong.
(f) Cost of such special materials with freight as may be required for repairs to furnaces, in the proportion of 30 °。 additional to that shipped from England for carrying out
the works.
Note.-Ordinary bricks and an average quality firebrick can be obtained locally, but all special firebricks for the furnaces and hottest parts of the flues must be shipped from England.
11. The estimate is to be in Pounds sterling, based on the assumption that the furnaces are to be erected in London, and the freight of special material to Hongkong should be added at the end.
12. It has not yet been decided to erect a Destructor in Hongkong, and no guarantee is given that any tender will be accepted. The plans and estimates may be of a preliminary character, but the details given of working and cost must be as accurate as possible.

NOTTINGHAM, November 1st, 1898.
DEAR SIR,-We have now much pleasure to hand you Specification, Estimate, and Drawings for proposed Destructor Plant for the City of Victoria, Hongkong.
We have gone into this scheme with a great amount of care and we think we have been able to give you such machinery that would work successfully if adopted.
Our reason for coming to this opinion is based upon the successful results we have obtained with a similar class of Plant erected in a somewhat similar climate and we believe that no other specialists of this class of machinery have had such good results.
Among such Plants we have erected, is one for the city of Kurrachi, India, where the Destructor
is dealing with the refuse at the rate of about 11 tons per cell.
We are equally successful in the City of Durban, South Africa, and as a good proof of the work done in that part of the world we are at the present time engaged in the execution of a contract for a Destructor Plant to be crected at the City of East London, Cape of Good Hope.
