material with a little rouKh stuff from the potting bench 

 and pot the plants firmly, leaving the space of an inch 

 at the top of the pot for water. Watering should be 

 done sparingly until the plants fUl the pots with roots. 

 By this time the plants .should be 4 inches tall, and the 

 center shoot should now be pinched out to induce enough 

 of the side shoots to form the foundation of the plants. 

 The center shoot will produce 2 or 3 side shoots below 

 where it was pinched, and with C or 7 bottom side shoots 

 will form the basis of the plant. Rub off any other side 

 shoots as they appear. After the plants have grown to 

 a height of 6 or 7 inches they must be staked and tied ; 

 a stake in the center for the center shoot and one for 

 the side shoots will be sufficient. After the plants have 

 attained a height of 10 or 12 inches, and before the flower 

 heads begin to show, pinch the center out of all the 

 shoots with the finger and thumb at the same time so as 

 to induce the plant to flower all at one time, for if pinched 

 two or three wprks .np.art the flower heads will come 

 irregularly and tli.- ;.lni- • -ri'l not look so well. As soon 



as the flower In i ! ' :, ■ . i ..a- the plants should )):i\-i-

 nure in a bag and drop it in a barrel of water for two oi- 

 three days before using. This makes a very good liiini.l 

 food for the plants; also chicken manure treated tho 

 .same way but used in lesser quantity— about a h;ilf a 

 iMishi'l to M ^'iillons of water will be about right. If i ho

 to ^t;o^lllu' and training, the grower will be amply i. 

 war.lod with nice specimen plants having from 12 to jo 

 Uower spikes to a plant. 



Seed-savitui. — Plants wanted for seed should be care- 

 fully selected. Only the very best plants with clean, 

 healthy foliage and large bracts or flower heads, with the 

 florets set close together, are the ideal plants for sood. 

 If the plants are growing in a house or near oth.r i>l,uits 

 that are not so good they should be covpred w itii mos- 

 quito netting to prevent the bees from cross-l'i rtilizini,' 

 them. After the heads have set, say from 20-2."i i""l~. 

 the center should be pinched out, for if allowed to •.'nw 

 and set more the seed will be of an inferior qnalit). 

 When the seed begins to turn brown in the seed-pods ihn 

 pods should be picked off and laid in an airy room for a 

 day or two on paper, so that none may be lost. After the 

 pods are dry, so that the seed will rub out clean, the seed 

 should be cleaned, put in a package and placed in tin 

 boxes to keep from mice, as these pests are very fond

MILDEW. This name is given to a group of fungous 

 diseases which attack leaves, shoots, flowers and fruits. 

 The true or powdery Mildews (Erysipheae) appear as 

 a thin, white, powdery coating on the surface of the 

 plants. The disease is usually accompanied by dis- 

 tortion and dwarfing, and often death of the affected 

 parts. In some cases, however, as in the maple Mildew, 

 the affected areas of the leaves retain their chlorophyl 

 and remain green in the autumn long after the rest of 

 the leaf is dead and yellow. The mycelium is always

 propai,':it.Ml by l-.^.-U.-d spon-s, many of which are cut off 

 in succession from erect, simple branches all over the 

 diseased surface. Other spores, by means of which the 

 fungus passes through the winter.' are prodncfd in sacs

4 fls., surrounded by an involucre of 4 bracts. The genus 

 contains about 60 species, mostly found in the warmer 

 parts of America. Shrubs or herbs, the latter twining, 

 rarely erect: Ivs. opposite, usually stalked: heads spi- 

 cate, racemose, corymbose or panicled: fls. mostly white 

 or yellowish. Nearest to Eupatorium, but the latter has 

 an indefinite number of involucral bracts instead of 4, 

 and contains erect plants.
