Research into better cf lubricating mine ropes is being pressâ€" ed by the petroleum industry and they, along with the Ontario Research Foundation, and the _ Inspections Branch of the Department of Mines, as well as the rope manufacturers, are collaborating in an effort to inâ€" crease the qualities and safety facâ€" tors of mining ropes. Oneée of the greatest contributions of Ontario mining men to the safety of hoisting operations is the new ‘dogs‘ which act as brakes on mining cages. In the case of the Paymaster acciâ€" dent, once the cable broke the dogs fail2d to ston the plunging cage. They were so built as to grip the shaft guides the very instant the rope broke. Unforunately, . notwithstanding _ the fact they did grip, the wood torn from the guides filled the teeth of the safety catches and rendered them useless. The new â€" safety â€" catches, evolved through research, consist of one or more teeth and a sharp cutting edge which immediately sheds the wood torn from the guides by the enâ€" gaging teeth. More than sixty percent of Ontario mines are now using this type of safâ€" ety catch and it is expected that soon all our mining cages will be so equipâ€" ped. New regulations call for at least three tests following the instalâ€" lation of these dogs and they are the most severe tests called for by any minire â€" regulations in the world. Maximum speed and load conditions are called for and must be carried out in the presence of one of the mechâ€" anical engineers on the staff of the Mincs Inspection Branch,.

Dr. Riddell, who is now a profess at the University of Toronto, began by saying that he was interested in the Porcupine Camp from way back. He said he had married the daughâ€" ter of Murray Clark who wrote minâ€" ing law books in Ontario and investâ€" ed all his money in mining stocks.

Having travelled widely broad he said that he had seen many things which had influenced his thinkâ€" ing on world affairs. 1 "We have all gone through two wars and we know what aggrossion‘is," he said.

Any threat of war became the interest of the League but pooh poohed any idea that the Japanese were using incidâ€" ents to cover up the fact that they were taking over the counry from the Chinese. The Japs moved into Manâ€" churia while the League delegates kept saying that it wasâ€"just anoth incident." Even though Dr. Riddell was quite sure what the Japs were up to. the senior delegate for Canada would not be convinced that the Japâ€" Ottawa boasts its best tulip display in years and with her tiny waltering can it would ie cher a long time to water the 400,000 Dutich blooms that enrich the natural beauty of the drive: park ways ‘ the Canadian caflhl every spring.

One of them is to tell th epeople that they are a great civilizing force and another is to tell them that they are a master race." "In Mussolini‘s mission to civilize Africa the Walla, Walin incident started the ball rolling. But the League had learned a few things from the Japanese incidents and this time it seemed as if something might be done. But they said they couldn‘t see any blame on either side." "Mussolini made up other incidents, Italy was declared an aggressor and pressure was brought to bear. Musâ€" soline then used the fear technique and warned them that many things would happen if they did anythin: A treaty was made with Mussolini but he had had it changed to read tha aggression in Europe was the onl reason for League sanctions, leavir him free to carry on his war against Â¥he Ethiopians. \â€""I was . much annoyed about the: sanctions," Dr. Riddell declared, "they lacked the very things that would stop him. .

His idea was to tal one thing at a time and Chamberlain paper was all a part of the technique These techniques are thought out well inâ€" advance. What caused the breach between Russia and Hitler were the demands made upon Hitler by Russia. Hitler decided that rather than give in to the Russian demands he would go to wWwar Dr. Riddell mentioned Himmler‘s speech before his death when he said: "Next time we‘ll plow our furrows deeper." The Russians, he said, are plowing much deeper. "This is a much cheaper way than using armies. I am not as afraid 0‘ atom bombs as I am of this kind of warfare," Dr. Riddell said.. "It is for the control of men‘s minds and we must wake up to the situation. We are beginning to get a defensive alâ€" liance of the Western countries, These Russians are masters of the game and are nothing to pooh pooh ~â€"â€" we must face it â€" it is the most real thing we have to face today."‘ "I look upon Moscow and the Sovâ€" iets as the greatest competitors weo have today. No country in the world believes more in its destiny to rule the world.. They are internaâ€" tional and they believe they have a plan for the world and one that will be only good when they have the world to work in. "In business we try to put out a better product but it is hard to conâ€" vince many people that our way of life is a better thing." Dr. Riddell then suggested that what we needed was a better informâ€" ation service to tell the people what is being done. ‘"I found low wages and manyv cljildren starving. We are not perfect but we should get the Russian attiâ€" tude that it is our manifest destiny and to tell the world that they wili get more out of our way of life than Oout of the Communist system.
