It is believed to be the most significant American deposit yet found of the fauna of the Triassic period, critical in the development of the ancestors of the dinosaurs and mamals...
...problems put up squarely to engineering science was that of landslides at the east bulwark. Last year while the excavators were scooping earth from a large gulch that runs 175 ft. below the low water surface of the river, 200,000 cu. yd. of clay began to slide down at the rate of two feet an hour, faster than the power shovels could get it out. The contractors were faced with a delay of several weeks and an additional excavation cost of $200,000. The engineers decided to try an old trick invented in Prussia but never before used...

In this descent toward mediocrity, the oratory prizes have stood out against the current like rocks in a stream, steadily maintaining their solid basis. They were washed over the blasts of rhetoric, by stultified, memorized arguments, but they remained fixed. Now, nurtured by Professor Packard's courses, and with the tremendous flowering of radio, which is based entirely on ear-appeal rather than the flourishing of arms, the true clocution which the prizes were founded...
