In the manuscript of my report of November 30, 1875, was given a summary of main sewer rates, wbich should have appeared on page 373 of the printed report of the Commissioners of December 1, 1875, but which was, through some inadvertence, omitted. It is contained in this table.

MAIN SEWER RATES. First. The cost of the work as obtained by a detailed estimate of its excavation and masonry, viz: Rates for bricks, per M...................................................... $23 Rates for stone, per perch...................................................

6 50 Rates for excavation, for 16 feet deep and less, per cubic yard ........

and for all over 16 feet deep, per cubic yard....... Rates for shoring, per linear foot .........

...................... 1 08 Second. An addition of 15 per centum for contingencies.

Third. A further addition of 15 per centum on account of the manner of payment.

The following are the bids upon which cash contracts were awarded by the Commissioners, after due notice by advertisement, and are considerably lower than the average of all bids received. It will be seen that they are generally in excess of the board rates:
