Additional Notice regarding St Tilda. 179 
winter, even on their hardiest vegetation, that savoys and 
German greens, which with us are improved rather than de- 
teriorated by the winter’s cold, almost invariably perish soon 
after the commencement of autumn. This, however, is not 
owing to the rigour of the climate, but solely to the salt spray 
which the boisterous winds carry up from the turmoil of the 
raging shores, and spread upon the surrounding vegetation. 
The minister has endeavoured to prevent this by recently 
raising a stone dyke ten feet high around a smail enclosure, 
in which his cabbages lie ensconced. In other respects, the 
climate is in truth extremely mild. The ice, which is formed 
even during the coldest night in winter, is scarcely thicker 
than a penny piece, and usually disappears entirely, if the sun 
is at all visible in the course of the ensuing day. 
The following table, kept by Mr Mackenzie, the clergyman 
of St Kilda, shews the temperature and direction of the wind 
for the months of January and February 1840 :—
