HUDDERSFIELD. — " It is a singular fact that trees about Hudders- 
field during the storm on Monday appeared as if covered with hoar 
frost, but as it did not freeze, it led to an examination, when it turned 
out that this was a briny deposit which the wind liad probably brought 
from the Irish Sea." 
Boston. — " Not within the memory of the oldest person has this 
place (Alford) been visited with such a tremendous gale as set in 
from the west on Tuesday morning, tlie (Sth inst (Monday, the 7tli 1), 
about 3 o'clock, and continued unabated until 11 at night. The 
most remarkable feature in the phenomenon here was that before 
2 o'clock every tree and hedge in the bleak situations were encrusted 
over (like a hoar frost) with a powerful alkali which an eminent 
chemist pronounced to be muriate of soda. It was easy to collect 
it by drawing the branches over with a piece of dark woollen cloth, 
which soon became as white as if chalked. Several times something 
has been observed within seven or eight miles of the German Ocean* 
when the wind has blown from the east, and it was supposed the 
wind absorbed it from the vapours of the sea : but the wind having 
now blown from the west, if such was the case, it must have been 
conveyed completely across the island from the Irish Sea. It 
appeared that the greater the elevation the greater was the deposit 
or concrete, which was clearly confined to the bleak side, particularly 
*An instructive comment on this newspaper observation is affoi'ded by 
analyses of the rain-gauge A\ater of Inglcby Oreenliow Vicarage, in Cleveland, 
448 feet above sea-level and some 20 miles from tiie (German Ocean. The 
samples were kindly collected for me by the Rev. J. Hawell, who, knowing 
the object in view, also supplied me with the meteorological data in the last 
column.
