Liquid Tile. A liquid plastic that dries into a smooth, hard, waterproof, tile-like surface was put on sale by Ev-R Shield Products, Inc. of Joppa, Md. "Glascote," painted by brush, swab or roller onto porous materials like plaster, plaster wallboard, seasoned wood, concrete or pressed wood, develops a poreless finish that, says the manufacturer, is invulnerable to all known solvents. Price...
...their own money to explore the area. Even in E.N.I.'s successful gas operation, there has been trouble. In the rush to draw off natural gas from the Po Valley fields, E.N.I, failed to seal a well properly. As a result, methane has leaked through large areas of porous upper strata, ruining crops and wasting...
...about "stratagraphic traps." Oil pools are comparatively easy to find by geophysical methods if the oil has accumulated in a "structural trap," where pressure has forced the rock into a domed or up-slanted formation. But some of the biggest pools of oil have been found in masses of porous material, e.g., limestone reefs or sand bars, that were covered ages ago by oil-tight sediments. Such underground treasures (the prodigious East Texas field was one of them) seldom answer clearly when they are queried by the geologists' instruments. Many of them have been found by pure accident...
...bottom, will build up a flat-topped reef (like many that exist today). In some cases, he says, such reefs were raised above the water, probably by changes of sea level because of ice ages, to become full-fledged islands. Then furious tropical rain went to work on the porous coral, dissolving it. The center of the island eroded faster than the rim, particularly if it had picked up a layer of soil. Reason: the soil contributed acids that attacked the limestone...
...unfortunate that it takes a constitutional crisis to alert conservatives to a moral issue. Conservative morality, economy-minded as it is, is not so much wrong as it is porous and shallow. Merit is figured in terms of loss or gain. So, mink coats, a legitimate political issue, is raised as a moral issue, an oblique one when compared to a basic moral issue such as the violation of a Truman order protecting FBI loyalty files from unauthorized persons as McCarthy. When a fundamental moral issue as McCarthyism arises, it is ignored. No one, as yet, has measured the loss...
