appear to support the view held by all who have investigated the question on the spot, that
there is no reason to apprehend that the construction of such breakwater would be likely to endanger the harbour by causing a deposit of silt; this however be further tested by the construction of a small part of the proposed breakwater as an experiment. It would probably be necessary in the first instance to make trial borings in order to ascertain the depth to which stones would be likely to sink; if the result of the borings should show that the cost of a continuous breakwater would be prohibitive, a fairly effective obstacle might still be formed by placing at intervals masses of stone, disposed in two or three lines so that the masses in one line would cover the intervals in another.
