The old aud well-tried remedies of pruning or buruing, or i)ruDing and buruiug, will answer every purpose against the Web-worni in ordi- nary seasons, where it is thoroughly done and over a whole neighbor- hood. It must, however, be done upon the first appearance of the webs on the trees, and not, as was done by the Parking Commission of this city last season, after the first brood of worms had attained their full growth and many had already transformed to pupfe. The nests at that time had assumed large proportions, and their removal entire injured the appearance of many young trees. Then, too, they were piled upon an open wagon, which was dragged for many hours around the streets, permitting a large proportion of the worms to escape. On the first appearance of the webs, which should be looked for with care, they should be cut off or burned off, and if cut off they should be burned at once. The "tree pruuers," manufactured for the trade and well known to all gardeners, answer the purpose admirably. The customary method of burning the nests is by means of rags saturated with kerosene or coal tar and fastened to the tip of a long pole. An old sponge has been substituted to advantage for the rags, but probably the best substitute lor this i)uri)ose is a piece of porous brick. lu a pointed communication published in the Evening Star, of August 21, Major Key, agent of the Humane Society, thus describes the making of a brick torch : " Take a piece o
