I have examined portions of the intake at different times round the beach. It is very dirty. I cannot speak positively as to its state previous to the em bankment. In some parts there is refuse thrown there — part has come down by the Ligar canal, and part has been carried there by carts at night. The place has 7 been looked upon as one to deposit filth upon. I have had the copies of the plans in my hand. They carry the street from Queen Street to Britomart Point. Three culverts were specified of three feet bore. If the embankment was carried across without culverts, all the sewage would be kept in. The natural tendency of the embankment, so far as carried out now, would be to cause a deposit of any solid matter held in sus pension. The culverts are 3 barrel drains. None of them are less than 9 inches above the floor. They were open at one end, but to be closed at the outer end by doors to be hung. So long as they are as at present there would be no current through. The moment the current tegan to run, the. tendency just on the wash would be to lift the door, but as soon as the water be-. ganto run in, the door would close. They would ab tplutelyihut out the .miter. The sewag* would be

confined as before. If the intake was full of water the culverts would run off all the water except the nine inches above the floor. It would not have the effect of scouring the floor. I only know of an additional culvert by hearsay. That one (shown on the plan on»a level with the floor) would not scour it either. I have made calculations as tothevelocityof the waterthrough the culvert, and the speed with which it would run over the intake. I calculated from the area and depth of the. intake, and the discharging powers of the culverts, and found tha,t the head of water at an average tide at 3 feet, and assumed that the inner sluices had been kept shut till the water. outside had fallen below the level of the culvert floor. I found that the speed through the culverts was 590 ft. a mm. and in the in take only four inches.
