Paris Green mixture: One pound of Paris Green, eighteen to twenty cents, made into a paste with warm water and stirred into one hundred to three hundred gallons of water or Bordeaux mix- ture, is a safe mixture, the stronger solution being for the elm-beetle. If water is used, the addition of one pound of milk of lime is recom- mended to prevent injury to foliage. Fill a barrel nearly full of air-slacked lime, fill entirely with water and let it stand until settled; the clear water above the lime is the milk of lime; or, two pounds of fresh lime to one pound off Paris Green, slacked in the usual manner, then strained through cheese cloth and diluted to fill a pail, may be substituted. Paris Green (or better, if attainable, Scheele's Green, because cheaper and more effective) acts more quicklv, but is also more dangerous to the foHage than is the Arsenate of Lead, although the addi- tion of milk of lime reduces the injurious eft"ects. Yet it Fig. ;Bordeaux"spraynozzle, requires more nicety in prep- aration and use, and is also more easily washed off. But, if the Arsenate of Lead is not readily attainable, Paris Green (if unadulterated) is a sufficiently satisfactory all-round insecticide. Since it has been shown that insects will avoid poisoned food until driven to it by hunger, it is essential to extend the spraying to all parts and to all food Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Fernow, B.
