THE EASTEE LILY IX XORTHERN CLIMATES. 21 formation of new roots, which ap[)ear in early September, has been the guide, and digging has been done wlien this occurs. This is probably to be looked upon as a reaction to more favorable temper- atures for growth ratiier than an indication of maturity, but. never- theless, stocks dug in early Se[)teniber, as the summer tempera- tures abate, have behaved perfectly under forcing and field condi- tions the next season. When dug at this season though, the bulbs must be looked upon as not fully mature and as comparable to much of the imported'stock from Japan, which also is dug while in full vegetative vigor. Digging has been done from September 10 to October 30. The performance of the bulbs dug during this period is about the same, so far as has been observed, but no careful comparative tests have been made. When the bulbs are dug late there is commonly a small per- centage of the stocks in which growth has started from the next season's crown. This growth is more likely to take place in the propagation than in the old bulbs. There is little doubt that there is in this characteristic a basis for selection, to which attention is now being given. To sum up this matter, it can be said that the bulbs can be dug from September 10 to October 15 or 20 and that the late digging probably gives the best-matured bulbs, although those dug earlier apparently develop satisfactorily. METHODS OF PROPAGATION. Any plant to become widely useful must be able to make rapid in- crease. Lilies in general have been considered the aristocrats of the flower kingdom because of their l)eauty and the difficulties in pro- ducing them, but the Easter lily can be grown from seed so as to blossom in less than a year and can be produced vegetatively in one season. There are many methods of increasing the stock. SEED. Propagation by seed has been dis
