Il mirtillo di uva e ribes (Nematiis-ribesii), un altro straniero pestif-eroso, ha fatto la sua comparsa in alcune località. Abbiamo, inoltre, un nativo Saw-fly (Pristiphera grossidarice), che assomiglia al suo congener europeo, e lo emula in malapena la larvaof questa mosca si nutre di entrambi il curry A.

Whether it has appeared among us yet, I am notinformed. They fight it abroad as they do the ordinary worm. The gooseberry and currant saw-fly (Nematiis-ribesii), another pestif-erous foreigner, has made its appearance in some localities. We have, besides, a native saw-fly (Pristiphera grossidarice), whichresembles its European congener, and emulates it in mischief The larvaof this fly feeds upon both the currant and the gooseberry, but prefersthe latter. Nature is liberal, and has given us, in addition, a native gooseberryspan-worm, the larva of a small moth. These several worms, unchecked, would soon render the culture of the currant and gooseberry impossiblein the regions where they abounded; and, at first, horticulturists werealmost in despair, for the pests seemed proof against the usual insecticides Currants and Gooseberries. 243.

I used nothing else on my plantation of over two acres last season, and wantnothing better; but it must be used daily as long as any worms are seen. I have heard that, if applied in a liquid form, a heaping table-spoonfulof hellebore to a gallon of water is a good proportion.
