This department is doing a very large amount of dredging all over the country, and I understand that the department has under its control some [DOT]dredges. I would like to ask the minister how many dredges the Public Works Department has? I do not know whether it is the intention of the government to increase the number rather than to have so much of the dredging done by private contractors. We find all over this country that dredging is done at very varying rates per cubic yard, and I have no doubt that if the government did this work itself, it would be done very much cheaper. Where there is so much of this work to be done, I think that the government could get it more cheaply done if. the department had its own dredges and did its own work. I would like the minister to give us an idea of how many dredges there are in his department, and where they are. Then we could judge whether we should advise the minister to have more dredges, so that his own department could do more of the work.
