FOG MADE TO ORDER.

In some of the fruit growing districts abroad, where the frost does much damage among the orchards, there exists a curious mode of protecting the trees from the cold. It is none other than the creation of an artificial fog. A cart is packed with i wot straw, and at the bottom is a I kind of stove filled with burning tar, ; and fitted with a revolving fan to ! regulate the draught. As the cart I moves along a dense fog is caused by the heat from the tar passing I through the wet straw. The vapour ; thus created rolls out in huge volumes and clings to the neighbouring I trees. The frost is thus thawed from the branches, and the fruit is saved from injury.
