to cleanse them, and fit them for the glass jars at home. The shore should be fished first, and the operation should be conducted with as much quiet as possible; any disturbance will be sure to drive away many of the livelier creatures. Take a small net attached to a walking stick or short rod, and thrust it out from you as far as possible over the water; then quickly dip and draw it towards you, and land it at your feet at some little distance from the edge of the water. Sort out the contents of the haul into separate jars, though, as you cannot have as many jars as the kinds which the net will bring up, a little judicious grouping will be necessary. Spawn of all kinds may be placed together in the same jar with mollusks, tadpoles, caddis worms, and colymbetes; most beetles must be kept by themselves, on account of their voracity, as must also the several kinds of carnivorous larvæ, such as those of the Dytiscus, and the dragon fly, and water worms of the genus Nais.
When the sides have been well fished, the deeper water may be operated on by means of the drag-net, and the produce disposed of in the same way.
On arriving home, sort over the jars seriatim, and dispose of the specimens according to the capacity and arrangement of your cabinet. The glass jars should be each furnished with a few tufts of some growing weeds, and with clear water. Some of the specimens will require to be washed to remove offensive matter, and some few will need a bottom of small pebbles, and a jar nearly filled with healthy vegetation. Anacharis, Myriphyllum, Nitella, Chara, Riccia, and choice Confervoids, are the
