The report of the Commissioners has been completed. Messrs Marshman, Bell, aad Lowe were aaked to report on the best outlet and take evidence as to the original overflow of the drainage, to enquire as to the effect of the works done, and the expediency of those ! contemplated by the Board, and generally to report as to the most efficient system of drainage for the district. They report prin cipally in favor of the lines of action follawed by the Board, and add in their concluding remarks the following recommendations :— That the embankments across the Cast flood way and eastern side of cross drains generally, should not be raised, and that for the present, and until the capacity of the main drain shall have been increased, No. 1 drain should not be enlarged, nor anything done that would eend into main drain more water than now goes into it. Aβ far as might be possi ble the shingle banks in the lower parte of the drain should be immediately cleared away. The operations of the Board onght to be directed primarily to keeping the bed of the drain dear, and concurrently, as funds admit, to the reduction of the bed to the gradient shown in plan attached. As the Board can afford it the drain should be widened, the material taken out to be used in strengthening the banks. They think that Government should be re quested to cause the railway bridge over Eyreton branch line to be lengthened to clear the drain ; also, that a catch drain be out on south side of main drain, and possibly on the north side, discharging into the Waimakariri, near the mouth of the Ohoka stream, to take storm water from lands that are too low to admit of being drained into the main drain. The Commissioners thought that, if possible, Dockey Greek might be diverted into South brook, on sub-creek running through 'sections 5543 and 5535, and the creek near Bennett's railway station, recently diverted into the watershed of the Oast, be diverted back again by its original course to within the watershed of the Byre. The quantity of material to be shifted in the enlargement of the main drain would be 246,000 cubio yards, and it would then disoharge 166,000 feet per minute, equal to nearly two inches of rainfall over the Cust watershed in twenty-four hours.
