The formula is copper sulphate 4 lbs., fresh lime 4 tt>3., water 40 to 44 gallons, and Paris green 4 ozs. Tent Caterpillars.—The most remarkable occurrence of the season was of the two common species of Tent Caterpillars Clisiocampa americana, Harr. (Fig 49) and C. disstria, Hbn. r (Fig. 52) These two kinds of caterpillars which were about equally abundant, stripped bare many acres of Aspen Poplar, Basswood and Maple Fig- 52- groves along both banks of the Ottawa Eiver and along the Canadian Pacific and Canada Atlantic Railways in the counties of Carleton. The Ash-gray Pinion.—Maples were also extensively injured at Aylmer, Que., and at Hull, Que., by the green caterpillars of Xylina Grotei, Riley, and X. antennata, Walker. These caterpillars are known as Green Fruit "Worms, on account of their de- structive habit of eating large holes in the sides of young apples and pears. In the Ottawa district they did little harm in orchards, but stripped almost bare large forest trees at the two places mentioned. This i i an uncommon attack which has not occurred in anything like the severity of last season since 1885. The ashy-gray moths do not ap- pear until late in the season. There are three species very similar in general appearance. All of these may be taken at sugar- in the Ottawa District in September and October. The caterpillar of the Eye-spott
