PROGESSEDIION The Canadian Statesman, March 2, 1977 7 St. Marys Cernent Company Seils Its Products to Many Ontario St, Marys Cernent Company wvhich began in St. Marys, Ontario in 1912, came to Bowmanvil le as the resuit of a search carried on in 1963 for a possible plant location to the east of Toronto. It wAas known that suitable limestone existed at varying depths along the nort h shore of Lake Ontario, covered by tills (glacial drifts of dlay), and in places by shale. Test drilling along a twelve mile frontage indicated the best possible area to be just west of our city. Options were taken on these lands and more extensive block drilling was carried out. It proved that ample reserves of excellent Trenton limestone were available, covered by tilîs which were also ideal rawv material for a wvet process cernent plant. Rock is quarr ied east of the plant to a depth of 70 feet, and hauled to the primary crush- ing plant. It is crushed a second time by a reversible impactor. Beit conveyors then deie silo wihe tpothae ail Qed itlo th pohe mal cornbined storage capacity of 9,000 tons. Raw grînding is the next step followed by the aujto- Companies matically controlled addition of milI feed and water. The resulting slurry is then fed i nto the kiln rs through hydra u 1- i cal11y control led val1ves. CI nk- ers are discharged into a cooler and the'n onto a belt conveyor system to eltier a clinker stock pile or directly to clinker feed silos. Finished cernent isstored in eight silos and two star silos having a- total capacity of 44,000 tons. 11 is loaded either into roadi tank trucks or railroad cars by a system of air slides and telescopic spous. Ail production func- fions except primary crushing and cernent loading are con- trolled from a central confrol- panel. St. Marys is an ail-Canadian privafely owned cernent manufacturer.

Canadians get $375 miion a week f rom life insu rance Canadian's life insurance comipanies make payments to policyholders and bene- ficiaries totallingy $37.5 million a week, reports The Canadian Life Insurance Association. Last year, life insurance benefits totalled $1,949 million, whîch is $179 mil- lion more than the previous year. Since 1960, benefit payments have increased k..by 250 per cent. Says the Association: "These increases reflect the growing use of life insur- ance. flot only for its pri- miary purpose of providing funds for the famnily whose -breadwinner dies premna- turely, but also for a vani- ety of family needs duing the lifetimie of the policy- holder." About one dollar in every three paid out by life companies is paid as a death settiement to bene- ficiaries. And almost two dollars of every three go to living policyholders as pay- ments of matured endow- ments, ainnuities, disability benefits, cash surrender values and policy di-vi- dends. I A SNt.
