The pots should be thoroughly watered, giving sufiicient to moisten the soil all through, after which they should be allowed to drain for an hour or two before sowing the spores. The spores are sown thinly on the sur- face of the soil, the sowing being done in a place that is free from drafts, else many of the spores may be wasted. Then place the seed pots in a sash-covered frame in the greenhouse, and cover the pots with panes of glass, the idea being to protect them from sunshine and also from drying out until the spores ger- minate. In fact, the tender young growths that first appear, somewhat like a green fungoid growth on the surface of the soil, should never be exposed to full sunshine, nor should they be allowed to become very dry. In case it should be necessary to water the seed pots, the best plan is to dip the pot in a pail of water, to avoid any watering of the surface at thin time. A night temperature of 00°- 65° is best for the spores, and a few degrees warmer in the day will do no harm. When the seedlings are large enough to handle, that is, about the time the first frond appears, they are trans- ferred in small blocks to other pans or flats in which they remain until enough growth has been made to enable one to pot them, these early operations in fern growing being a matter of rather careful and tedious work. The time required for the raising of ferns from spores to a size large enough for potting off into 2-inch or 214-inch pots varies with the species and also with the season, spores that are sown in the autumn taking more time to develop than those of the same species sown in the spring, but some Oif the quick-growing pterises will be ready to pot in six months from the time of sowing, while others may
