Lionhead GoldfisK OvJned and Photographed by F. Schaefer Having read of the advantages of using sheep manure as a cultivator for aquatic plants in the household aquarium, I decided to do some investigating along this line, as I had always had poor suc- cess with Sagittaria under certain condi- tions of light. Some years ago I had an eighty-gallon aquarium built to fit into a square space containing three windows v/ith western exposure. The dimensions of this aquarium were not what they should have been, the depth being too great in proportion to the width; besides, it was subjected to the full glare of the afternoon sun. Plants, with the single exception of Anacharis, never grew well in this tank. I tried Sagittaria many times with the same result; they never shot off runners, and gradually died out each time. Accordingly I set up two twelve-gal- lon aquaria in the following manner: In number one I placed a layer of sand about one-half inch thick; then over this I sprinkled a thin layer of pulverized sheep manure, just enough to cover the sand well, then about an inch and one- half of clean sand over all. I planted this aquarium with Sagittaria and placed it in a strong west light, exposed to the afternoon sun, a position identical with that of the unsuccessful large aquarium. In aquarium number two, I placed two inches of clean sand, planted Sagittaria without adding the sheep manure, decid- ing to feed these plants directly by in- jecting a saturated solution of the manure among the foots by means of a special syringe consisting of a thin glass tube about fifteen inches long, with a rubber bulb on one end. I filled both aquaria with water at the same time, and
