down now, especially in the greenhouse.It is very _necessary to open the ventilators a little in um morning, and more if possible in the afternoon, • on any reasonable dile This serves the useful purpose of -egulating the temperature, and also stimulates the circulation of air Ventilation is essential for the well-being of plants; with very few exceptions they thrive in a buoyant atmosphere ' Hanging moisture is a persistent enemy. The disease called "dampingoff " is not exactly caused by moisture; but it is definitely encouraged to spread by it.' Surplus water is to be detected in a variety of ways. Obviously it hangs in beads of condensation on the glass which air currents will quickly remove. It also is seen on the panes of glass which cover seeelings. These panes should be turned once a day. Moisture in excess of= causes a film of green to appear on the surface of the soil—a condition whico a, however, often due also to sourness and excess of nitrogen. ,Prick up the surface of the soil to admit air, Ilse lime when possible, and in very severe cases use a very dilute solution of permanganate of potash twhil..h should not be deeper than the palest pink). Moisture is usually found where seedlings are overcrowded. Tiny plants such as lettuces, celery and tomatoes growing ifeloors are often allowed to grow too big before they are moved on As soon as two or three genuine leaves appear, the young plants should be movect on by pricking out about four incite. each way in good soil.
In a way, there is one point in favour ot having seedling's fairly close together; they are protected by each other. Bur the advantage is of _doubtful value, because the sesailinge soon begin to " draw " One anothed This is often their ruin '' Drawing " is also caused by having indoor seedlings too far front the glass. They should be as near it as possible. Seecitings outdoors are prone to stiffer from overcrowding too. In particular I mention turnips hecause these are among the very first lo appear. Though not exactly first tavotaites turnips well grown aadesucettlent tire acceptable early in the year. Only too often they are horrible or they go to seed because they have not been thinned in very good time. They should be at least six inches apart. Spinach needs thinning twice—first to three and then to six inches. Peas and beans are not likely to be too close together when frost and birds and mice have finished with them , but if they are. thin the peas to about three, inches apart in the rows, end the hearts to six or eight. Where the spit is moist enough, you can plant out cauliflower seedlings wintered in frames from last year, also onion seedlings.
