Geologist: Earth once hod two continents Two and one-half billion years ago the earth had only tw.o major continents: Gandwana and Lauiasia, according to geologist Hunter Yarborough who spoke at Morrill Hall Tuesday night. "We believe," said the senior geological scientist with the Humble Oil and Refining Exploration Group, "that those two major land masses broke up into smaller continents and drifted apart." The crust of the earth floats almost like a raft on top the soft molten inside of our planet, the geologist said. Yarborough said the earth's crust can be divided into six Government switches food stamp policies Two new regulations governing issuance of food stamps which may affect student users go into effect Wednesday. The new requirements state that all members of households on the program must be related and that users listed as tax dependents of their parents cannot qualify for the stamps, both during the year they are claimed as dependents and the following, according to Harold McGrew, state welfare department spokesman. McGrew said the related household rule is designed to curb stamp use in communal living situations. He speculated that the tax dependent clause is aimed at eliminating students "whose families could provide support." Hopefully, he said, the dependency requirement will not eliminate any users really needing the supplemental food purchase program. Basically the food stamp program operates on a formula based on income and size of family. The family purchases stamps with cash, which are in turn used to purchase edible foods. Stamps will not buy imported foods except coffee, tea, cocoa and bananas, McGrew said. The federal program also requires a user to be a county resident, live in a home with cooking facilities and have a net adjusted income below specific limits set according to size of family. The Lancaster County Public Welfare office estimates that there are currently 150 student families on the food stamps in this county, although the figure fluctuates monthly. for the finest in popcorn. . .

The plates which are 40 to 50 miles thick move, the geologist said. They can't be seen to move on earth, but they can be detected by seismographic listening devices, Yarborough said. There is a lot of data to back up this ; idea of "continental drift", said Yarborough. The African and South American continents could be fitted together with very little space left between, he said. The geologist said same age and type rocks have been found on the African coast corresponding to like rocks in the matching area on the South American coastline. If placed together, said Yarborough, a known fault in South American would match an adjacent fault in the African continent, making a continuous line. ,. At one time there may not have been any Atlantic Ocean, he said. The Atlantic Ocean is getting slightly larger every year now and the Pacific smaller, the geologist said. Yarborough pointed out that Baja California could be fitted along the Mexican coastline, and there is evidence to show it drifted away. The scientist refers to continents as having a leading and trailing edge. According to him, California is the leading edge of this continent which means it will eventually be drawn into the ocean. The San Andreas Fault in California has trapped a lot of oil in the Los Angeles and Ventura basins, he said. Although, according to the geologist, oil companies have pretty well picked bare all the basin oil deposits on the continents, which has forced them to look for oil on the ocean floors. Studying the movements of the earth's crust is important to geologists looking for oil because much of it is caught in structural traps caused by the movement, Yarborough said. Archeology students take sandbox course Sandboxes will be used as a training device in an archaeology course offered during the interim period from Dec. 27, 1971 to Jan. 14, -1972, Anthropology Prof. Dale Henning said Monday. "This part of the course ought to be quite a lot of fun," he said. A series of 4x4 ft. boxes filled with sand will be used, according to Henning. "In them we will establish conditions similar to those in archaeological sites," he said. "The students will excavate them, using what they have learned in class to understand the sites and to identify the material in them." The course will "try to develop an awareness of what archaeology is all about," Henning said. Collections of materials from all over North America will be used to give students a feeling for the remains typical of North America, he commented. Henning said casts of rare artifacts and collections of real artifacts from camp grounds and village sites from 12,500 years ago until 1 ,700 years ago will be used. "They won't be professional archaeologists but they will have better than a layman's understanding." Henning will teach the class from 9 a.m. until noon Monday through Friday. The course is Practical Archaeology, Anthropology 198t5. Three hours credit will be given. 13 ikreiVOy At?C rr-Pw& III yC rKuVY mm I p li COLOR IN THIS "MINI 1. Buy a whole bunch of Flair pens.
