It is true that the gold fish has become naturalised in the Schuylkill above Philadelphia, or rather perhaps we should say in the Fairmount dam - - a distance of miles. They were introduced by the breaking of a fish pond many years ago. The boys offer them for sale in winter of a large size, and fit for stocking your lake, at from ten to fifty cents each. There are hundreds of natural lakes and artificial dams where they would multiply enormously. Last winter, while constructing some dams on a small stream of spring water which empties into the Schuylkill, we requested the Irish laborers to purchase any gold fish that might be offered, and place them in the dams. A few days only elapsed before the works were completed, and on taking a view of them our intelligent superintendent related the following adventure. The cold had been intense, and had frozen the river to an unusual depth; the gold fishes, big and little, repaired to the mouth of our little stream in great numbers, probably for the greater warmth of the water; the freshet having meantime subsided, the man went to the river to see its effects, when lo! the ice had fallen and had caught in a trap at the creek's mouth, ten dozen fine large "goldies," which were taken by the hand, filling a large washing tub, and thus our new water was stocked at once.

Why should not the smaller lakes of Western New York be stocked with these beautiful pets?

(M. M.) It will be an improvement to your process in resisting the Apple borer, if you cover the cloth which you wrap round the boll of the tree, on one side, with a mixture of one ounce of grease to two pounds of rosin. The cloth is placed with the rosin-side outward, and overlapping; the adhesive qualities will keep it in its place, and assist much in repelling the pest of our fruit trees. The process will be less troublesome than looking up the grown enemy with knife and crooked wire.
