"Max" says: "Doubtless one quart of tobacco juice to two gallons of water will kill a black aphis if you get it to him, but to apply it is the question. Our experience is that simply syringing will not kill all or nearly all. We got rid of them from young peach buds by wheeling a force pump along the rows and by the force of the stream, knocking them off. This was followed by an immediate sprinkling of tobacco dust which prevented their return. This method is impracticable after the trees have attained one or two years' growth. Can't something more easy of application be found? Query: does the aphis attack the tree first and descend to the roots or vice versa, or does it attack both simultaneously?"

[The subject is one of great importance and he who shall succeed in solving the problem may make a fortune for himself, and get the thanks of our fruit growers besides. It has been found in every branch of horticulture that any operation that depends upon water for its appliance, is usually too costly. At one time liquid manure had many advocates both in horticulture and agriculture, but it was found the cost of hauling so much water outweighed the advantages. So also in the case of the potato beetle - all liquid forms of applying the Paris green proved too expensive. In the case of a few trees we can yet use liquid Paris green where the enemy is an eater - but insects that suck, like the aphis, these poisons are of no account. We have to use some narcotic like tobacco that will affect them through their breathing organs. We have faith that some cheap plan of doing this may yet be invented, though as "Max" suggests, in the liquid form it costs too much probably. - Ed. G. M].
