...every season since 1932 have enriched its ancient history, traced the outlines of its prehistory. Ireland was not inhabited in Pleistocene times, as Britain and Europe were. Settlers arrived from Britain about 7000 B. C., bringing Stone Age implements some 10,000 of which the Harvardmen found. In geological strata of this period pollen grains of elm, alder, beech and oak and fossil shellfish reveal a warm climate. The Bronze Age began about 1800 B. C., the Iron Age not until 100 A. D. From then until the Anglo-Norman conquests (12th Century) the Irish lived in wicker huts, wooden...
...knocked off the helmets of London bobbies who tried to intervene. At Cardiff the captain and crew of an Italian steamer were driven below decks by brawny longshoremen who swarmed aboard and plastered every door and hatchway with posters reading "Down With The Fascists!

...Casagrande found that a hard dry piece of clay when compressed becomes soft mud because clay is made up of minute mineral particles and voids filled with water. Compression gradually forces the water out, the rate of consolidation depending on the depth of the strata and the weight supported. A classic example of the subsidence is the Tower of Pisa, which furnishes fairly accurate data on the factors of weight and shape. Mistakes in foundation engineering are responsible for more damage and loss of life than all other causes combined...
...police departments, ham-strung by the venality of city bosses and the inferior talents of their men, are unable to function with the essential efficiency and coordination. Offering a meagre salary and little hope of advancement without political influence, the police forces are compelled to recruit from the lower strata of society...
