PAGE T \VC: slre Safely Valve Fragments of Glass TO THE EDITOR: The onlooker's explanation for the explosion of Rea and Derick's heat strengthened polished glass door is most ridicu lous. Air is not "pumped into" the glass. To temper a glass plate it is heated uniformly until it begins to soften. There is free molecular movement and the entire mass is expanded. The plate is quickly moved to a position between two blasts of air which must be uniformly distributed over the surface with equal pressure on both sides. The surface thus becomes chilled and rigid. Due to the poor heat conductivity of the glass, the in terior portion of the plate cools more slowly and remains molten for some time. Solidification of the surface by rapid chilling fixes the dimensions of the plate while it is ex panded. As the interior cools, it shrinks and tries to draw the surface inward. This it cannot do as the surface is already fixed in size. Tempered glass is many times stronger than regularly annealed glass and can be deflected near ly six times as far without breaking. When a severe blow fractures the edge or surface, the characteristic "lace curtain" type of fracture occurs disintegration into relatively small and harmless fragments as compared to ordinary annealed glass. —R.

YVONNE DeCARLO DAN DURYEA "Criss Cross " nit/any KRISTINE MILL ER ARTHUR FRANZ "Jungle Patrol " Business Manager tlOr Vance C. Klepper _ Myrna Tex Clarice Liinch Spring Week's Comin` Spring is here at last! Its arrival brings more than budding trees, buzzing bees, nesting birds, sweatered coeds and lightly turning young men's fancies. To the campus it brings the first annual Penn State Spring Week, which is destined to take its rightful place amohg the re nowned festivals of the eastern colleges. Big plans have been laid for a tremendous All - College celebration, with a sufficient variety of events to stimulate 100% participation. Among the outstanding features of the Week is the fact that some of the profits which will be realized as an incidental part of the fun, will aid unfortunate students in the Philippines, through the World Student Service Fund. The list of events is an imposing one, starting with a Faculty Talent Show and intramural wrestling finals, building up to a gay street Carnival, climaxed by the IFC-Panhel Ball and music by Tommy Dorsey. But that's not all. The last two days of the Week offer a break fast radio program from the TUB, a bebop concert, houseparties (independent as well as fraternity) and the Men's Glee Club concert. Much hard work, original thought and careful planning have been poured into the project to assure its success. It will have been futile if students fail to get into the spirit of the festivity. Never let it be said that Dartmouth and Cornell can outshine Penn State in "Big Weeks." University Baptist "Religious Resources in Our Li brary" will be discussed by Elsa C.
