Floriculture. 74 The Florists' Review AroTJST 14, WW. to eliminate and stop further damage by white ants when once -these iaaects kave become established in the WAOilwerrk-of a building. The approximate point of entrance should be nought at once by careful examination of all woodwork in contact with the ground. It may be necessary to tear up the flooring and other woodwork to do this. The foun- dation timbers and interior woodwork found damaged should be removed, and the ground whoro they were set drenched with kerosene oil. The main purpose must be to prevent the insects from gaining further access to the woodwork from colonies in the ground. This may be accomplished by replacing untreated foundation timbers with stone or concrete. If it is not practicable to substitute stone founda- tions, foundation timbers in contact with the ground should be replaced with timbers impregnated with coal-tar creosote. In greenhouses iron frames and con- crete work should, wherever possible, replace woodwork. The wooden up- rights supporting the wooden plant benches should be sawed off, if set on or in the ground, and rested on stone, bricks or concrete above the surface of the ground. Where woodwork is neces- sary, wood that is impregnated with a one per cent solution of bichloride of mercury should be substituted. Wood thus impregnated can be painted after treatment. Poles, posts, construction timbers, and other wood in contact with the ground should be treated with chemical preservatives to render the wood more resistant to attack by termites. Of the more superficial methods of preserving timber, brush or dipping treatments with coal-tar creosotes and carbolineums have proved most effective. The most permanent known practical method is to impregnate the wood under pressure with coal-tar creosotes. Where it is im- practicable to treat such timbers as poles, posts, etc., to be set in contact with the ground, they should be selected from woods noted
