The plan of Mr. Janin, C. E., waterworks superintendent, Montreal, for an increased supply of better water, as well as a greatly increased water power for pumping the drinking water, with estimated cost, has been submitted to two experts, John Kennedy, C. E., consulting engineer of the Montreal harbour commissioners and Ernest Marceau, C. E. Their report is given be low as follows: “The essential features of Mr. Janin’s project, as set forth in the information supplied to us by him, are: (I) The construction of a closed conduit along the north side of the aqueduct from the pumping station to the bank of the St. Lawrence, just above the entrance works of the aqueduct and its extension out into the river to an intake point, where it will be supplied by St. Lawrence water unmixed with shore water and water from the Ottawa river. The shore part of the conduit is to be of watertight concrete construction, and about 57 sq. ft. area of internal section and to have a fall of x in 3,000. (2) The enlargement of the aqueduct from its intake at the river to the pumping station to a cross-sectional area of not less than 1,008 ft. below the under surface of the ice at low water, which is assumed to be at elevation 33 ft. above waterworks datum at the entrance, and having a fall of 1 in 8,333. (3) The remodeling and increase of the hydraulic power pumping machinery at the pumping station, to a capacity of at least 50,000,000 imperial gals, per twenty-four hours and connections for supplying the pumps from the new conduit, also connections with the pumping mains leading to the city, and the rearrangement of the steam power pumping machinery, to conform to the new conditions. (4) The enlargement of the tailracc to the capacity necessary for the discharge of the water from the enlarged aqueduct. (5) Wells, waste-gates and other works requisite for the proper working of the enlarged aqueduct and increased pumping machinery. We are of the opinion that Mr. Janin’s plan as thus outlined is entirely feasible, and that it is an excellent one for improving the quality, increasing the quantity and reducing the cost of the city’s water supply. We are of opinion that the projected works will supply waterpower to pump to the city 50,000,000 imperial gals, per day of twenty-four hours, under the most unfavorable condi lions— that is. at the lowest recorded stage of the river in winter and when the aqueduct is covered with ice, which is the capacity stated in Mr. Janin’s reports. Mr. Janin, in his report of 18th March, 1907, states that the enlarged aqueduct will develop 5.000 horsepower in summer; we are of the opinion that this estimate of power is correct for the most unfavorable summer condition that is. the etdarged aqueduct will furnish water to develop 5,000 effective horsepower at the waterwheels, when the river, at the entrance of the aqueduct is at its lowest recorded depth of 35 85 above datum. Under ordinary summer conditions that is, with higher water, the power which can be developed will, of course, exceed 5,ocx) horsepower. We have checked the estimate of cost of the conduit from the river bank at the intake to the well at the pumping station, and we are of the opinion that Mr. Janin’s estimate of $660,000, is correct. The estimate for the other items will be dealt with in a further report, after the necessary details have been prepared and furnished us. The details of the works, at the entrance of the aqueduct and the intake of the conduit are not yet fully worked out; but, from the fact that the position of the present aqueduct intake is a very favorable one, and that no trouble has ever been experienced from frazil entering it, we are of opinion, that the works can 1K‘ so designed and built, that their operation will not be seriouslv interfered with by frazil.

The existing plant can be modified and enlarged, without its operations being interfered with. The present open aqueduct is 40 ft. wide by 8 ft. deep for drinking purposes. As it now is. dust and dirt get into it; dogs are swum, and boys even bathe in it, although each practice is forbidden. The watercourse, after the proposed enlargement, will be 140 ft. wide by 14 deep. The whole volume of water will be used for pumping pur poses only, doing away with both steam and electric pumps. The proposed covered conduit for drinking purposes only will be 10 ft, in diameter, with a capacity of 50.000.000 gals.

General Description of the Plant. Specially written for FIRE AND WATER ENGINEERING.

The present waterworks of the city of Montreal were begun in the year 1853, and have been progressing from year to year to this date.

The present water supply of the city is taken from the river St. Lawrence, about one mile above the head of the Lachine Rapids, at a point about thirty-seven feet above the summer level of the Montreal harbor, and brought down in an open canal or aqueduct, 26,200 feet long to the Lachine canal, at Gregory’s Farm, where are placed the wheels and pumps hereinafter described. The dimensions of the canal or aqueduct are twenty feet wide on bottom, forty feet wide at the water surface, and an average of eight feet depth of water. The water perimeter of the canal is faced with stone, with interval slopes of one foot and a quarter vertical for one foot horizontal, and tlie slope of tlie bottom is about five inches per mile. There is another canal or aqueduct of larger dimensions tapping the river St. Lawrence at about 3,000 feet higher up than the one above described, and joining it at 4,800 feet below its entrance, giving an additional foot of more head of water to the whole aqueduct. The dimensions of the second aqueduct are as follows: Width at bottom, seventy-eight feet; at water level, 130 feet; depth of water fourteen feet; inclination of bottom, two and one-half inches per mile; side slopes from bottom to three feet below surface of water, two feet horizontal to one vertical, from three feet below tlie surface of the water to four feet above it, one and one-quarter foot horizontal to one vertical, from this last point to the top of bank two feet horizontal to one vertical. The portion of the side slopes with the inclination of one and onequarter to one is lined with a heavy dry stone wall. A still water basin, 600 feet long by 400 feet wide, built in the St. Lawrence, forms tlie entrance to the second canal. The water in these canals or aqueducts is controled by two sets of regulating gates—one set placed at the entrance of the smaller aqueduct, and the other on the large one, near its junction with the small one. Two stone bridges and a third bridge of stone and iron are built over these aqueducts at their crossing with the public roads.

GEORGE JANIN, Superintendent Montreal, Can.

At Gregory’s Farm, the lowest extremity of the aqueduct, near the city limits, are placed the pumping works, consisting of waterwheels and steam engines. The water machinery consists of four waterwheels and nine pumps—that is, one turbine, with three pumps, and three turbines, with two pumps each. The total capacity of the waterwheels is 15,000,000 imperial gallons per twenty-four hours. The whole of these wheels and pumps arc inclosed in a substantial stone building of the Grecian style of architecture. The water from the wheels is returned to the St. Lawrence about half a mile above the Victoria bridge, into an open tail-race, 3,500 feet long. The water fall from the aqueduct into the tail-race is seventeen feet.

The steam machinery consists of three steam Worthington pumps, as follows: One Worthington duplex, compound direct-acting, horizontal engine, with two pumps, and two Worthington liigh-duty pumping engines. All these engines are double-acting, with a combined capacity of 28,000,000 imperial gallons per twenty-four hours. The engine house buildings are built in brick on stone foundations, and are placed at about too feet west of the Wheel house above described.

From the pumping mains the water is forced into a reservoir built on the slope of Mount Royal mountain, through three pumping mains, one of thirty inches internal diameter, and two of twentytour inches internal diameter, and 14.100 feet long. The route of these mains is as follows: The thirty inch flows through Atwater avenue front the pump ing works to Sherbrooke street, passing under the Lachine canal, where it is laid in duplicate. At the crossing of St. Catherine street it is connected with the city mains .and then runs along Sherbrooke street to Papineau road. At the crossing of Shcr brooke street and McGill College avenue it is connected to the two twenty-four inch mains going up to the reservoirs. Connections are also made with all the city mains east of McGill College avenue. The two twenty-four-inch mains from the pumping works also follow Atwater avenue to St. Catherine street, also passing under Lachine canal, then turning into St. Catherine street and following that Street un to McGill College avenue, where they are branched off into four branches following McTavish reservoir, connecting at Sherbrooke street with the thirty-inch main as above mentioned, and with the iweive-inch main of Sherbrooke street. The two other branches follow St. Catherine street, eastward. At Phillips square one of these twenty four-inch mains is subdivided into one sixteen-inch one twelve-inch, and two six-inch mains. The sixteen-inch runs down Leaver Hall to McGill street, along McGill to William street, feeding along its route the pipes in the centre of the city. The twelve-inch main distributes water along St. Catherine street and tlie six-inch along Beaver Hall and Radegonde street. The other twenty-four-inch is extended to Bleury street; along Bleury street to St. James street; St. James street to St. Sulpice; down St. Sulpice street to Commissioners street; along Commissioners street eastward to Berri street, feeding all the pipes in the centre of the city. A twenty-four-inch pipe from the Wheel house runs along Centre street to Montmorency street, up Montmorency, across the Lachine canal, and along Guj street to St. James street, and thence to McGill street, connecting with all cross streets.

The reservoir is placed on Me l avish street at an elevation of 204 feet above the level of the water in the Montreal harbor, or about feet above tlie level of tlie water of tlie aqueduct at the Wheel house. It is twenty-four feet deep, dug out of the solid rock, and is divided into two compartments by a strong wall of masonry. The contents arc about 36,500,000 imperial gallons, when full.

The water is distributed into the city both directly from the reservoir and the pumping mains and through various mains, whose total length is 227.44 miles. The number of hydrants for fire purposes is 1.722; the total number of house services is about bo,200; and the daily consumption of water is at present from 22.000,000 to 24.000,000 imperial tz:»lIons.

At the McTavish reservoir is placed another ett gine house with a high-pressure Worthington, du plex, steam pumping apparatus of the capacity of 500,000 imperial gallons per twenty-four hours, and a Gilbert engine that was built in 1887 of a capacity of 2,500,000 gallons per twenty-four hours. The water is forced from the Me l avish reservoir to a smaller reservoir placed in the Mount Royal Park at the head of Peel street, 218 feet above the level of the McTavish street reservoir. The high-level reservoir contains, when full, about 2,000,000 imperial gallons. A twenty-inch main from the engine house carries the water to this reservoir by following McTavish street to Pine avenue and then to Peel street, where it is divided in three branches of twelve-inch mains going up Peel street to the high-level reservoir, and the other two running along Pine avenue eastward and westward, connecting with all the main pipes crossing Pine avenue, so that all the houses above the level of Sherbrooke street on the slope of the Mountain are supplied from this reservoir. The twenty-inch main on Mc Tavish street is laid to Sherbrooke street, and a branch twelve-inch is carried down town, via Peel and Windsor streets, to St. James street as a fire main.
