. Dennis' silk manual;. Silkworms. [from old catalog]; Silk industry. /. Dennis^ JrJs Patent Improved Method of Preventing Canker Wor^ns, or other In^ sects, from ascending Fruit or other Trees. This invention consists of a cirr.ular metallic trough, and roof, made of one piece of metal, and sfenerally made of lead, and bent so as to conform to the shape of the tree^ and the ends soldered together, so as to make a trough com plete- ly round the tree, with a roof over it, and made so large as to leave an inch between the trough and the tree, which will allow the tree to grow five or ten years : the space between the trough and the tree is filled with hay, straw, liusks, tow, cotton waste, sea weed, or any substance that is easily compressed by the growth of the tree. These troughs should have a very little right whale oil, that costs about forty cents per gallon, put into them three times a year; five gallons of oil was found suf- ficient for one bundled and fifteen trees for a year, and some of the trees were very large, and it kept the worms down so completely, that it was difficult to find one upon the trees. This trough is put on at a small expense, and a very small crop of apples will pay the expense of putting them on: and they'will last many years without being made larger, and when the tre§ has grown so as to fill the space that is left, the trough ca/i be cut open and a piece put in, so as to make it large enough for several years more, and when the lead is taken off, it will be worth two-thirds as much asit was when it was put on ; the expense for fittingit around trees that are one foot through is about fifty or sixty cents.
