Rock-Crushing Plant of Messrs Laurin & Leitch

General Description

The rock-crushing plant of Messrs Laurin and Leitch engineers and contractors, Montreal, Canada, is unusually interesting from its enormous capacity of production and remarkable flexibility of operation.

Having obtained from the Montreal Water and Power Company, the contract for constructing within four years a reservoir of 43,000.000 gallons at Outremont, one of the city’s suburbs, they recognized the advantage of crushing and marketing the rock at the time the excavation is made instead of piling it on a waste bank, the usual custom in the past.

As the reservoir will be 800 feet long, 400 feet wide and 40 feet deep, formed partly by excavation and partly by enclosing walls, it will be necessary to crush within four years approximately one million tons of hard trap and granite rock and to provide storage for approximately one hundred and fifty thousand tons in various sizes after crushing so that it can be marketed to the best advantage.

The limited time at the disposal of the contractors and the enormous quantity of stone to be removed within that time necessitated the erection of one of the largest rock crushing plants in the world.

The site of the reservoir from which the rock is quarried is upon the north slope of Mount Royal, and quarry operations have been started at the lowest point in the reservoir site, where an excavation of approximately twenty feet has been commenced.  From this point the quarry face will be gradually cut back towards the mountain parallel with the lower edge of the reservoir.  The rock as fast as quarried is loaded direct by steam shovels into six yard side dump quarry cars, which are made up into trains of four each, to be hauled to the crushing plant.  The rock is drilled by Temple electric drills along the quarry face which is 800 feet in length, and after blasting the cars are brought to the proper location alongside of the steam shovel, close to the bank of blasted rick, by Shay locomotive, which is 6’ the geared type so s t take the grades, pushing the empty cars up to the quarry face, and bringing the loaded cars from the quarry face to the bottom of the incline haulage system leading from the lowest point in the reservoir to the crushing plant.

Hoisting System:

The crushing plant is advantageously located upon an excellent site about 1500 feet from the centre of the reservoir, and to bring the rock from the excavation to the crusher a haulage system has been installed operating in balance, drawing a train of four loaded cars up the haulage incline of about 4 per cent, to the foot of the two incline trestles leading from the ground to the dumping hopped over the large crusher.  At the same time, a train of four empty cars is lowered down the haulage incline back to the quarry, balancing in part the up-going load. At the upper end of the haulage incline there is a third track for empty cars, and the trains of loaded cars which are gathered upon first one then the other of the two outside tracks shown upon the cut accompanying this article, are hauled up these incline trestles of approximately 20 per cent grade, one at a time and alternately upon each of the two trestles as shown in photo 776, so that the large crusher is receiving a carload of rock first upon one side and then upon the other, making its operation almost continuous.


The reservoir, which will be the largest in Montreal, was designed by Frank H Pucher, Chief Engineer of the Montreal Water and Power Company.  Approximately one-half of this reservoir is to be completed first and put into operation, while the remaining half is being completed.  The main water pipe leading from this reservoir is now being laid by Messrs Laurin and Leitch, and consists of a line of 60-in cast iron pipe, the laying of which, with its valves, etc., is in itself as item of considerable interest, but which is dwarfed in comparison with the quarrying and crushing operations going on.

This plant is unusual in many respects: primarily on account of its size and initial cost in proportion to the amount of work to be done under this contract.  The size of the plant and the excellence of its equipment are resulting in a saving in the cost of construction of the reservoir, and the disposal of the rock taken from it which should pay for the entire equipment.  It has sufficient capacity to crush the rock as fast as taken from the quarry, so that the product can be marketed immediately after excavation.  The rock is handled but once from the excavation to the marketing, and in this way it is immediately disposed of and is out of the way.  The rock is excellent in quality and instead of being thrown away on a waste bank, as was the case of the rock taken from the excavation for the Chicago drainage canal, for example, is made to yield a profit. Messrs Laurin & Leitch use a very great quantity of crushed rock in their own work on other contracts, noticeably, street paving, concrete work, and other engineering work of similar character, and a portion of this rock will be used in this way, the cost of which will be less to them than rock purchased upon the open market.  The plant, which was designed and equipped by the engineering force of Allis-Chalmers Company, possesses an unusual flexibility of operation in addition to unusual economy of production, so that it may be operated to suit both the work of excavation and the market for crushed stone, producing rock for the lowest possible cost of production.  The plant is exceedingly compact, resulting in the smallest possible buildings, and is well arranged for operating with the smallest crew of men. One man handles the hoisting and haulage equipment, tow men the dumping of cars and feeding of crusher, two men the handling of cars at the foot of the incline trestles, one man for the spring floor, one man for the number sixes, one man for the transmission and hoist floor, one engineer, two boiler men, one oiler and two men upon the conveyors, loading, etc. and these men constitute the entire operating force of the plant. One side of the haulage incline may be operated independently of or without the other. Any one or all of the number of sixes maybe cut out temporarily, and when the balance of the plant is shut down rock may still be loaded or piled on the storage piles, or the drills at the quarry may be operated.


Is it just me? Best Buy Commercial, 2019

There is this back to school – HP Days commercial for Best Buy which has been airing recently, which features this young man purchasing a laptop computer and apparently some other electronics.  After his purchases are made through the assistance of a helpful sales clerk that exists only in fiction, he is seen setting up his equipment in a classroom and with flashing lights and cool graphics he introduces himself as Professor McKinley.

I keep running this through my head.  Not because of his cool laptop or the great service being offered by the store, but because it tells me so much about how we expect our teachers to buy their own equipment.

Why is a “professor” buying his presentation equipment?  Why does he need flashing lights and cool graphics to impress his class?  Is he really impressing his class? Why is the professor a young white male?  And it goes on.

Am I the only one questioning these narratives, stereotypes, etc in this commercial?

New Life for Droopy Hairdos….

We’re in the mood to discourse on permanents today … mainly because we’ve had so many over the years… and have finally found one that doesn’t start off by looking so stiff and set that you tell people “it’ll soften out after the next shampoo” … or conversely, so soft that it’s practically non-existent and the next shampoo is all that’s needed to brush it off completely… we got a very superior permanent at the House of Glamour several weeks before Christmas… known as a body permanent, in that it doesn’t really make your hair curly but holds line and shape, which is what all the new hair styles consist of….in fact curls, as such, are dead as a dodo… we’re completely happy with it, and think you would be too… another plus about the House of Glamour’s permanents… they’re comfortable and fast… you recline in a comfortable chair, sipping coffee and scanning the latest magazines… and first thing you know you’re finished and looking more excitingly glamorous than you ever though possible… or leaving glamour aside, certainly beautifully and smartly groomed… a nice way to start this nice new year would be a House of Glamour permanent, and a new hair style by Danny, or one of his award-winning stylists at the House of Glamour, 655 View St

Englishmen leave their job suddenly

Remarkable Walk-out – Grievance of their fellow countrymen incenses workmen and they quit

Yesterday 13 employees of the Winnipeg Paint and Glass Company left their jobs on the part of one of their fellow workmen.  The men who left were all employed in the factory of the company.  It seems that on Tuesday there had been a dispute between an Englishman and one of the other men employed in the factory.  The Englishmen in the employ of the company all sided with their countryman, and the demanded the dismissal of the other workman.

The company refused to grant their request, and as a result all the Englishmen in the factory went out.  The company do not anticipate any trouble in filling the places of the men who have left.

Fashion Gossip, 1878

Newry Reporter, 24 October 1878 page 4

Fashion Gossip

Bridesmaids in France are now replaced by two tiny pages, who are chosen from the prettiest of the boy relatives of the bride or bridegroom, and are dressed in velvet of the bride’s favourite colour. At a recent wedding the tiny court dress worn was of sapphire velvet, with white silk stockings and velvet shoes with diamond buckles. A bouquet composed of a rosebud, an orange blossom, and a branch of myrtle is attached to the left side.  They perform the usual role of bridesmaids, carry the bride’s missal, bouquet, gloves, and in addition, meet her and assist her from the carriage steps.  The fashion of adopting reptiles for the tiny porte bouquet has been succeeded by something prettier and more happily inspired. Ladies are now replacing them by butterflies, bees, and birds with wide spread wings, in diamonds. HRH the Princess of Wales has adopted the dragon fly with its sapphire wings for her cognisance.  The Princess de Sagan, whom she honours with her friendship, takes the white rose of her family traditions and fastens it in her corsage with a ruby swallow.  The Duchess of Teck adopts the bee as the holder of her favourite flower, the daisy, which she wears continually.  And so, during the winter, we shall find les dames du beau monde choosing each respectively her own insect and flower.

The Secret of the Great Pyramid, 1930

I found this pamphlet in a vintage shop, and thought it was hilarious.  Most of the text goes into the mathematics of the pyramid and how it “proves” the currents of Christianity, bolstering the faithful through equations.  The author is actually ridiculing the people who rely on this to support their faith, but the descriptions are hilarious!


The Secret of the Great Pyramid

MDR Willink

London, Society for Promoting Christian Knowledge (circa 1930s)


The Method Tested – the Great Pyramid was known to the Egyptians as “Khuti” = “the Lights.” The obvious thing seemed to be to test the theory on the window.  The sill measured exactly 39 inches.  To what could this refer? The simplest cypher is the alphabetical.  39 can either be taken as 3 and 9, or 3 times 13.  There seemed no harm in taking both. Thus, 3=C, 9-I, 13=M.  CIM.  Wonderful! For many years the China Inland Mission occupied this very house! Let us go further.  The opening of the window is exactly 36 inches.  But as the window opens in the middle it is obvious that these two dates beginning with 18 are indicated. The first is easily found. A line from the sill dropped to the floor gives 53 inches – 1853 Hudson Taylor the famous CIM missionary’s first voyage to China. The second needed more research. An interior measurement omitting wainscot and sill gave 43 inches. Nothing special happened in 1843, but by including the sill we get 1844, the year of Taylor’s conversion.  What could be more convincing!  And if further confirmation were needed, the length from the window to the neighbouring door is 36 inches – an English yard – while a perpendicular erected upon it to touch the slope of the roof gives 25 inches – the ‘sacred’ pyramid cubit of the Hebrews – and the house, though rented by English people, belonged to a Jew.  The fact that the dates are given in inches is specially noteworthy, for according to the pyramidologists the inch and the 25 inch cubit are the units of revelation.


Thirty two inches below the junction of the passage with the Grand Gallery we find ‘the true AD Point,’ and the Grand Gallery itself represents the Christian Dispensation from AD 30-1844.  And here we find that the whole of the pyramid symbolism and prophecy becomes concentrated upon Great Britain – with America as a satellite – because we use the inch, practically identical with the Pyramid Inch , and that proves that we – and America – are the Chosen People, the Adamic Race, for whose great benefit and warning Shem-Khufu built the Great Cryptogram 4,000 or more years ago.


Of course we have always known that the British Race was something out of the common, but to be so very special that 4,000 years ago Shem-Khufu built a pyramid all about us is almost embarrassing to our natural modesty; and then to think that the long lost relation is discovered because 12 inches make a foot, and there are 64 gallons in a quarter of wheat!
