NOTE ON DRY VALLEYS IN THE CHALK. 
BY THE REV. E. MAULE COLE, M.A. 
The month of January, 1887, will long be remembered on the 
Challi Wolds of East Yorkshire, as presenting one of the most curious 
sights ever witnessed. A succession of frosts had frozen the bare 
ground so hard, that no rain could penetrate. What little rain fell 
was quickly converted into ice. The same thing happened with 
regard to subsequent slight falls of snow. The thermometer was 
never very low. The snow partially melted and froze again, till the 
whole was converted into what the Swiss call neve. The roads for 
miles and miles were a sheet of ice. The turnip-fields and grass 
lands were also covered with a coat of ice, and on the slopes of the
