1st., no dirt or rubbish of any kind should be thrown or 
laid on the thoroughfare : 2nd., they should be kept within 
the yards till the scavenging carts call for them : 3rd., the 
refuse water from houses should be led into the sewers. 
But where no sewers exist, how to dispose of the same? 
This is a most difficult question, especially as its solution 
involves one of outlay and money. 
I have stated previously that Port-oi-Spain had been 
divided into six sewerage districts, and that sewers had 
been laid in one district (No. 3), at a cost of £6,515 10. 
At the same rate the sewerage of the whole town would 
cost the sum of £39,093 instead of £15,000. But I do not 
hesitate to say that the sewerage of the other districts will 
cost more, either because some of them are larger, and at 
least far more crowded. But let us take the sum of £39,093 
as correct. The Superintendant of Public "Works has be- 
sides, in his report dated 29 March 1865, given it as hia 
opinion that an increased supply of water would be neces- 
sary, and the estimated cost has been put down by him 
at £23,678. Taking the estimate as correct, the sewerage 
of the whole town should be calculated as follows : 
cost of sewers £39,093 
probable cost of a fresh supply of water. 23,678 
£62,771 
If to that sum we add the sum of 43,875 
amount due for water-works on 1st January, 1865, 
we would then have a gross amount of £106,646 
or $511,900 owed by the Borough ; and, as already stated. 
the annual value of property, in Port-of-Spain, is only 
$385,000 ! I ask whether, under such circumstances, it 
would be prudent to insist on the completion of the sew-
