You asked if there were men in England when the country was covered with ice and snow. Look at this, and judge for yourself. What is it? a piece of old mortar? But mortar which was made Madam How herself, and not by any man. And what is in it? A piece of flint and some bits of bone. But look at that piece of flint.英文原著 · 《Madam How and Lady Why》
The chalk-flints decay externally, which, according to Berzelius ("Edin. New Phil.

From north-west to south-east the line of high hills runs. In the north-west corner, Snowdon towers among a number of heights over 3,000 feet. At its feet, to the north-west, the isle of Anglesey lies. The peninsula of Lleyn, with a central ridge of rock, and slopes of pasture lands, runs to the south-west. To the east, beyond the Conway, lie the Hiraethog mountains, with lower heights and wider reaches; further east again, over the Clwyd, are the still lower hills of Flint.英文原著 · 《A Short History of Wales》
