In the selection and growing of stock plants, the care- ful grower should always be on the watch for types which are most perfect in shape, in character of indi- vidual fronds, in coloring, freedom of producing spores, and exemption from the attacks of insects and fungous diseases. In a large number of Ferns a great difference between the different plants of the same species will be apparent to the careful observer. Some plants of same species have beautifully developed fronds, but are carried on long, weak stems, which makes them unfit for general use. Others may be of compact, sturdy. 813. A home-made Fern case. habit of growth, but with poorly shaped individual fronds. In some individuals the coloring will be greatly superior. By closely studying all these points and by continually selecting only the most perfect types of Ferns from the 3'oung plants, we can in a few years work up a very desirable and superior stock. The same stock plants of the rapid-growing varieties of Ferns should not be carried over for more than three or four years, V)ut young and more desiralde plants sliould con- tinually be selected and grown to take their places. The stock should be shifted into larger pots when ever necessary, and placed in a light, airy house, in which all necessary conditions are under perfect con- trol, and in which a temperature in coldest weather of 55° F. at night, with a rise of 10 or 15° in daytime, can always be maintained. The house should be shaded just enough b.) prevent fronds from turning yell
