M. ALLO'S BELATED REPORT,

Wellington, July 13

The report from M. Edmund Allo, dated 2nd March, 1903, which for some unexplained reason the Government have kept back, was presented to Parliament yesterday. EAKAIA GIVER. M. AHo inspected the Rakaia river at (he point called "The Gorges." He says the quantity of water running through the river can be estimated at at least 6000 cubic feet of water per second. By building dams across tho two arms of the river on each side of the island, each dam would be about 300 ft long, and would require to be 42ft high above the woter level. They would therefore, contain about the same amount of concrete as the Waimakariri scheme dam, and the price cau be put down as being about tho same, or £110,000. This 6000 cubic feet of water, with 42ft fall, would give us aboub 20,000 h.p., delivered in the city of Christchurch at practically the same total cost. The water ira tho river should be barbed up 42 feat, and surveys should ho mado to ascertain the value and area of Mr McLean'<> property, which is situated behind the second gortje, find which will be partly swamped, and for which damages will have to be paid. The Rakaia scheme certainly presents advantages over the Waimakariri, in so far that it would bo much easier to build the whole hydraulic works. Having the two aroi3 of the river, the water could be ejected by one arm, while the other was being built"—facilities which we havo not got in the Waimakariri scheme. The power station could bo installed at the bottom of the cliff, on the email terraco standing about ten feet above water level. Across the second bridge a race cnuld bo cut, to deal with about 6000 cubic feet: of water per second. A bridge should bo built over this race i to connect with the road, and from the end of the race, through valves, he water would go direct to the turbines standing on the terrace below. Although this spot is fifteen mile 3 further away from Christchurch than the Waimakariri Gorge scheme, the small increase of transmission line would hardly have t© be considered, in view of the larger amount of horse power to be delivered in Chiistchurch—about 20,000, as against 14,500 h.p. "Mr Dudley Dobson and Mr Hales both concur with me in my opinion that the Rakaia would be the easier scheme of the two. I should, therefore, strongly recommend that the city of Christchurch should give Mr Dobson the necessary instructions to have a total and careful survey of the Waimakariri Gorge. I shall then be able to give a fuller report upon the Rakaia river than what I ootild do at present, when effective figures »*efAiling,"
