Mix one teaspoonful of paris green with three gallons of water ; as the plants get stronger, strengthen the mixture by mixing one teaspoonful of the paris green with two gallons of water ; stir well so that the whole will be of equal strength. It should be applied to the plants at intervals from the time they show their full leaves until the fruit begins to ripen. Apply with a watering pot, using a fine rose. When the mixture is judiciously used it acts as a stimulant, and creates a healthy, vigorous growth. Any practical gardener would know from the appearance of his plants how frequently the mixture should be applied. The inexperienced gardener should apply at intervals of eight or ten days. The mixture should be applied in the early evening, but must not be used on cool, damp days. The green fly will not succumb to moderate applications of this mixture, so I would advise that tobacco be sprinkled over the leaves of the plants to rid them of this pest. In this treatment the plants must be given good care and the applications be made regularly. - Philip Ryan.
