I find two animals that trouble my celery, and I can find no reference to them in the books. The first is what we call " Sow bug." It is a gray, flat bug, full size about ¾ inch long ; it eats on the outside of the celery stalks, low down under ground, very much disfiguring the handsome bunches. The second is a "one-thousand-legger worm" about 1¼ inches long, small ;' sometimes thin and thick and both disfigure the celery. Who can give me a remedy ? - J. E. M., Portsmouth, R. I.
J. E. M., Portsmouth, R. I., will find a remedy for celery pests in the following compound: Take equal parts of soot and sawdust, sprinkled with fine lime, unslaked. If he could get some rich soil from old decayed tree roots and put it around the celery at the same time, he would be astonished at the growth, He should cut the roots or nip them a little before transplanting them in the ground. He should also water them occasionally with the suds of a washing day, and urine water from cattle diluted with rain water. - William Street, Penn.
