and key as well as under his close observation, it doesn't mean that, although people in Hung Hom are using the area, that the people cannot also use the area to play golf. In fact it would be another sport to introduce into this Colony which is rather limited with regard to sport for the general public.
MR. SALES:-As a member of the Urban Amenities Select Committee I suggest that our charming colleague Dr. BELL knows as well as I do that there are three parcels of land at King's Park that have been promised to the Urban Council. One from the Education Department; one from the Medical Department and the third directly from Crown Lands Office. So for all three parcels of land the Urban Amenities Select Committee, during the period when Dr. BELL was not in the Council, considered plans for their development, and I suggest that the papers concerning these three parcels of land be sent to Dr. BELL for her comment.
DR. BELL:--I have already seen them Mr. Chairman, but I did not think they were completely fixed and perhaps changes could be made. I thought the plans would be elastic and not completely fixed as Mr. SALES has suggested.
MR. SALES:-Sir, I would prefer to let the good lady have the last word.
DR. BELL:-Thank you, Mr. SALES, it is a great honour as a female to have the last word.
(16) DR. A. M. S. BELL asked the following question:-
Will the Chairman please explain why certain Urban Services Department scavenging vehicles seem to leak dirty brown smelly fluid all over the streets even when going towards town?
DR. R. H. S. LEE, CHAIRMAN OF THE ENVIRONMENTAL HYGIENE SELECT COMMITTEE, replied as follows:-
The vehicles referred to are probably those used to remove manure and stomach contents i.e. undigested fodder from the slaughterhouses. In Kowloon between three or four loads are carried daily from Ma Tau Kok slaughterhouse to Gin Drinker's Bay. Two loads are carried daily in Hong Kong from Smithfield to the nearest dust boat station. Although the manure etc. is allowed to drain by stacking it in baskets prior to loading, considerations of time and space do not allow it to dry out, and it is still

in a wet state when loaded into the collection vehicle. Some leakage of fluid occurs at the joints between the body and the rear doors, or hopper. It seems that it is not practicable to provide a fully water tight seal although an attempt is to be made to provide a seal on one type of vehicle where there seems to be the best chance of effective modification. Experiments have also been carried out with a nightsoil collector. In this case the manure and stomach contents are first diluted with water. This protracts the loading time and increases by at least 100% the volume of the load to be carried. It has been found that settlement of the solids in the vehicle's tank is such that the air pressure used to discharge it is insufficient and there is chokage of the outlet pipe. There are vehicles employed in other countries for the removal of sludge which employ different mechanisms and might be used for this purpose.
It is proposed to consider this further. In the meantime, measures will be taken to allow the manure to drain as long as possible before leaving the slaughterhouses. Arrangements have been made for all vehicles carrying this waste to Gin Drinker's Bay to be washed out at the dump after off-loading to eliminate any dripping on the return journey.
DR. BELL:-Thank you, Mr. Chairman. May I take it from that that the vehicles do leak, and now you are going to wash them?
CHAIRMAN:
That is correct.
DR. BELL:-Thank you. May I also ask you, since it was suggested that there are vehicles employed in other countries which are slightly more efficient than these, are we considering ordering any of these vehicles?
CHAIRMAN:-I would have to look into your question and let you know the answer later.
(17) DR. A. M. S. BELL asked the following question:-
Will the Chairman please consider what can be done to improve street lighting on the Tai Po Road between the North Kowloon Magistracy and the junction with Castle Peak Road? This is a well known accident spot and the present inadequate lighting gives very bad pedestrian and motorist visibility.
