Moss and Lichens, especially in damp confined 
situations, where there is not a free circulation of 
air, and the sun’s rays are shut out. 
Mr. Thos. Bishop, in a communication to 
the Caledonian Horticultural Society, for the 
eradication of this disease, says, “ At any conve- 
nient time, between the fall of the leaves and re- 
ojjening" of the buds in spring, when the trees are 
perfectly dry, take a quantity of quick lime, either 
in shells or recently slaked, and thereof make a 
stronsf solution or mixture with water. Immedi- 
ately apply the same as a washing to the trees in- 
fested, either by means of a watering pot, with a 
wide rose, on the lower trees or bushes, or with a 
common garden engine, to those of greater height. 
If there are many trees to be washed at a time 
it is better not to make up the quantity of liquor 
at once, that may be necessary to wash the whole, 
but to add occasionally more lime and water into 
the vessel, stirring it frequently when used. The 
effects of this remedy will first appear by changing 
the colour of the Lichens to a darker green, and 
whenever tlie rays of the sun alight upon them they 
will assume a brown colour and shrivel up, as if 
scorched with fire ; from which time they cease to 
draw any more nourishment from the trees, but 
will in a few months begin to drop off, and will 
wholly disappear before the ensuing winter, when 
the bark of the trees will regain a smooth glossy 
appearance, and the vigorous shoots of next sum- 
mer will clearly exhibit the deliverance aftbrded 
them.”
