The Seaforth News, 1955-11-24, Page 3T1ILPARM FONT kollo From the number of hurting permits issued each year by vari- ous provincial game depart- ments, there are 1,000,000 hun- ters across Canada today. While these do mostof the shooting during the year, there are thou- eands of men in the far north who depend on their rifle or their food supply. Other thou- sands are satisfied to do their shooting indoors or outdoors at stationary targets or whirling clay "pigeons." e • Farmers, apart from any hunt- ing for sport they may do, find guns and ammunition important farm tools for controlling pests and predators, writes K. N. Mor- ris in the current issue of C -I -L OVAL. Mr. Morris says that crows which are found in most parts of Canada and magpies in western Canada, are notorious Thr their activities in rural areas and if not controlled can play ` havoc with the farm economy. Burrowing animals like the eastern groundhog and the wes- tern gopher dig holes in which livestock can break their legs, must be kept in check, In remote farming areas, livestock must be protected against the depreda- tion of marauding foxes, coyotes, wolves and bears. • • * Mr. Morris says that the hunt- ing instinct is satisfied by thou- sands of Canadians remote from the supply of game by trap and skeet shooting or firing station- ary targets. One advantage of indoor target shooting clubs is that they can find safe and satis- factory quarters in both large and small centres. The rifle and revolver section of the Canadian National Recreation Association bas its range in a mid -town Montreal building. Business and industry is recognizing the re- creational benefits of shooting and one new head office building in Toronto has been equipped with a basement rifle range for its employees.

Western Canadian farmers lust 140;000,000 bushels of grain last year due to the heavy infestation of weeds, H. W, Leggett of the Federal Dpartmnt of Agricul- ture, told delegates at the recent conference of the Canadian Agri- cultural Chemicals Association. Mr. Leggett who is superin- tendent of the government ex- perimental station at Regina„ said that of the 45,600,000 acres in the four western provinces planted in cereal c r op s, about 12,000,000 were sprayed with 2, 4-1) chemical weedkiller. This compares with , 500,000 acres sprayed in 1947. "By breaking down a few prej- udices, we should be spraying 30,000,000 acres of weed infested grain annually," he said: * • H. F. Stairs of the New Bruns- wick Department of Agriculture, stated that at one time register- ed seed growers in his province were non-existent because of the heavy weed infestations. Since the advent of 2, 4-13 New Brunswick has hecome one of the largestgrowersof registered seed on the continent. Chemical weed control has also resulted in the more economic production of potatoes in the Maritimes. • 8 • The use of chemical weed- killers has greatly simplified brush clearance on Hydro rights- of-way, J.

WE'RE GOING TO PUT THE ISUN TO WORK A small puff of condensing steam began to come from a rubber tube at one end of a large plate of glass and black- ened metal. It was the Israeli solar water boiler, set up as part of an exhibit in connection with the first world symposium on applied solar energy. "Hey!" someone shouted. "It's working It won't pull a train, but it's working" This spontaneous comment from the onlooker just about summed up the status of applied solar energy in general. In lim- ited practical applications and in a good many laboratory ex- periments, it is working. Any- thing like large-scale solar pow- er plants are still a long series of research projects away. But, to some extent, the sun is ready to be put to work today. That is why some 900 dele- gates came here from 36 coun- tries to talk over the possibil- ities of developing uses for this tremendous energy source, writes Robert L. Cowen from Phoenix, Arizona, to the Christian Science Monitor. All this past week, Old Sol has been getting more attention in the sun -drenched American Southwest than it has since the days of the Indian sun worship- pers. Sponsored by the Associa- tion for Applied Solei Energy, the Stanford Research Institute, and the University of Arizona, the conference split neatly into two sessions.

With an acre of Arizona sun- shine able to pile up the energy equivalent of 185,000 gallons of oil in a year, the experts here have treated their present ac- complishments as only the first small practical steps in develop- ing a very large vision. As Dr. Farrington Daniels of the University of Wisconsin, one of the leading solar -energy sci- entists in the United States ex- plained it, this is a challenge to the intelligence of men to use the abundance that is in the sunlight around us. The supply of this sunshine is enough to meet many of the en- ergy needs of mankind for mil- lenniums to come, he said. But it will take a long, hard research effort to take practical advantage of any really large amount of it. This, then, is the experts' es- timate of applied solar energy and its prospects as sketched by the five days of meetings -some limited applications immediately and a challenging promise for the 'future. "There is no sudden era of solar prosperity just around the corner," Dr. Daniels said, but added that he expects solar en- ergy eventually to tale its place beside atomic energy as an im- portant supplementary addition to ordinary forms of power. "Atomic energy will come in large, multi -million -dollar cen- tral power stations," he explain- ed. By contrast, he said, "solar utilization will probably start with small units costing not mil - ions of dollars, but only thous- ands of dollars. They will find their first practical uses in rural, nonindustrialized areas." He added that "unlike atomic energy, solar energy has no critical mass, no health hazards, - and.no waste products to dispose of.. Anyone cab go out in his yard and run a toy steam engine with free sunshine." But, there is another difference between atomic power and solar power that weighs heavily against the large scale use of sunshine, as was pointed out by Sir Edward Bullard, director oe Britain's National Physical La- boratory. Atomic, oil, gas or coal power can all be generated within the relatively small area of a power - plant furnace. Sun power, in large amounts comes only in correspondingly large areas. Sir Edward calculated that a solar- pou'er plant of 100.000 kilowatt capacity -enough to power a large town -would need about a square kilometer (about two - fifths of a square mile) of ex- posed sunlight -catching surface. Equipment of any kind, includ- ing solar -energy c o l l e c t o r s, "comes dear when bought by the square kilometer, he commented. This is the biggest disadvan- tage of solar power on the large scale. The energy of sunlight is spread so thinly that, for the foreseeable future, it would be too expensive to collect it for power purposes. But, despite this fundamental drawback, there are some labor- atory experiments aimedt pow- er. These are the basis for the hope expressed here that some day the, cost factor will be licked and' the sun harnessed directly for power. The Israeli water boiler is a case in point. It was developed by Israeli physicits manly to show that it is possible to reach boiling wa- ter temperatures with a flat- plate heat collector. Previously, only a focusing mirror or lens could bring water to a boil. The Israeli physicists found a way Of improving the effective- ness of their heat collectors, which are made of metal pipes attached to a blackened metal plate and protected from the wind by a single or double layer of glass. As a water heater, this is an effective device and, if mass produced, would probably not cost too much more than con- ventional water -heating equip- ment, according to its designers. But, as a generator of high- temperature steam for indus- trial power, the heater again suffers from the- need for large collecting areas to gather useful amounts of power. In this di- rection, it is another research hope that is a long way from realization, But, close by the Israeli ex- hibit, there were other pieces of equipment that illustrated the more immediate prospects of using solar energy. A row of solar cookers gleam- ed brilliantly in the midmorn- ing sun. These were mainly parabolic mirrors of cheap con- struction and about two to three feet in diameter with a pot - holding stand at the focus. An egg was boiling merrily in the model shown by Dr. Ad- nan Tarcici from Lebanon. It took just three minutes to start it boiling in the hot Arizona sun. This was much faster, Dr. Tarcici observed, than the 20 min'-ttes a similar dee. ration had taken in the cooler climate of Central Park, New York. But, like the smoothly work- ing Italian solar water pump or the model -house heating and cooling units in nearby exhibits, Dr. Tarcicis cooker, and others like it, will find their biggest usefulness in lands where the sun is hottest. Sir Edward and other speak- ers ranked such use of sun power as of prime importance for the underdeveloped areas that generally lie in hot cli- mates. Solar stoves, for example, if reduced from the $10 to $45 they now cost to under $5, could cut the fuel costs that drain heavily on the small money in- comes of families in these areas. They could also eliminate the use of animal refuse as a sup- plemental home -cooking fuel and release it for the more valu- able use as fertilizer for the food crops. House cooling using solar power can also be a big help to these countries. Sir Edward pointed out that working ' effi- ciency in hot areas goes up when cooling is available, to say nothing of the advantage of re- frigeration for preserving food, as more effective Means for do- ing this with solar units are Worked Out. It takes only the area of a roof to collect enough solar power t0 cool a house during the hot daytime hours and to collect enough energy for stor- age to operate the cooling sys- tem during the night, Sir Ed- ward observed. Solar pumps, which could re- place the man -plus -bullock it rigation systems in these parts of the world, have their - attrac- tions for underdeveloped areas, too. All of these functions and any others that could be performed by solar devices, can be served more effeuively by gasoline - or oil -powered motors. The ad- vantage of the solar units lies in the fact that they make no money drain on the country for their operation and can, in many cases, be built by native craftsmen. These - = the practical uses Of applied solar energy that are already economical, or just one or two development stages from being so, Beyond them are the broad dreams of harnessing the sunlight for power. These dreams are based on such things as the Israeli water boiler Or the experiments that have used sunlight to breakwa- ter into hydrogen and oxygen gases, thus turning this common liquid into a high-grade fuel. The Association fr'r Applied Solar Energy told the Phoenix symposium that, with the co- operation of the Stanford Re- search Institute, it plans to establish an international "lab - Oratory of the sun" somewhere in Arizona for a co-ordinated research attack On applying the sun's nergy. This will be a plate where such dreams can be followed, along with the more immedi- ately practical solar worn:. The important thing about the present stage of solar energy, commented Dr. Daniels, is that we have reached the point where it is working. Now it is time to "do something" sub- stantial about it, MERRY MENAGERIE "Gimme a banana and 2'11 go away[." AY >001, ESSON R.

Luke 10. Jesus Christ did pot wait for the people to come to him. He went to the people throughout their towns and villages. Once he was teaching by the seashore. The throng so pressed forward to hear him that he entered a boat and taught the people, Thte lesson he taught on that occa- sion concerned the four types at soil; the hard, the shallow, the thorny and the good. This wap the first parable he used. An nold's Commentary defines a parable as a short invented story which is true to life, from which a spiritual lesson is drawn. Jesus explained thlet first parable setting a pattern for their understanding. The hard soil of the wayside is rel9• resentative of the people who hear but do not heed. It is A warning against being indiffer- ent to God's word, In Palestine the rock is often near the service: The thin layer of soil represents peoplewhoon the impulse of emotion decide to follow Christ. Especially are they likely to make such a de- cision if others are doing it. But later when someone sneers at them they turn aside. The soil where the thorn* choked the seed represents the people who are burdened with the cares of this life or snared with its pleasures or deceived by riches. The word is choked. It is encouraging that there is always some good soil. Some will follow . Jesus all the way„ though they may vary in their fruitfulness. Later Sesus sent out Usa tlyelve disciples to preach t 3 kingdom of God and heal the sick. Science is slowly realizing the close relation Of 'a purse mind and a healthy body. We would not detract from the miraculous power of healing exercised by Jesus and the apostles.
