184 Notes and Gleanings. 



the pots, until, by placing the tuber on tlie soil, the crown reaches to within an inch 

 of the top of the pot. Then fill in between the pot and the tuber with the finer 

 portion of the compost ; give the pot a few smart taps on the bench, which will 

 cause the soil to penetrate amongst the fibres ; and finish by pressing the soil 

 round the tuber with the fingers, leaving the crown just peeping through the soil. 

 This being done, give a gentle watering with tepid water, and return the glox- 

 inias to their old quarters ; if in the bark-bed, place a small flower-pot, not in- 

 verted, beneath each, which will prevent worms from entering, and allow the 

 water to pass oiT freely. 



After the pots have been plunged for a fortnight, raise them one-half their 

 depth, and in another fortnight lift them entirely out of the bed, placing the 

 plants where they can have as much light as possible, but not near a flue or hot- 

 water pipes, as dry hot air is very injurious to the foliage. Examine the plants 

 daily, and see that none suffers from want of water. That used should always 

 be of the same temperature as the house in which the plants are growing. Be 

 also careful not to over-water, as, if the soil becomes saturated, tliey will cease 

 to thrive. 



As soon as the plants begin to show flower, remove them to the warmest part 

 of the greenhouse, as the flowers should expand in the same heat as that in 

 which they are to remain. In hot weather, a slight shade will be necessary dur- 

 ing the hottest part of the day. As the plants go out of flower, water must be 

 gradually withheld ; and they should be placed in a position where they can have 

 all the sun possible : this will cause the tubers to ripen and go to rest, which is 

 necessary to their future well-doing. During the period of rest, these must never 

 .be exposed to a temperature below 45°. 



Rhubarp. running to Seed. — It throws up flower-stems more abundantly 

 when planted in poor than in rich ground; but it will produce its large umbels 

 under any circumstances after it has been planted three or four years, some 

 kinds more than others. This weakens the roots very much, and should not be 

 allowed. Cut away the seed-stems, when you first perceive them, level with the 

 ground ; and this will induce the formation of crowns at their base, instead of 

 the energies of the roots being expended in the production of seed. 



Rhubarb should be grown in rich soil. Manure freely every autumn, covering 

 the bed with well-rotted manure, and especially covering the crowns of the 

 plants. In spring, point this manure into the bed. Propagation maybe eff"ected 

 by division in autumn or spring : we prefer the former season. 



Plants may be raised from seed ; but seedlings often possess unpleasant pur- 

 gative qualities, and experimenting with seedlings may be attended with dis- 

 agreeable results. 



The correspondent of " The Journal of Horticulture," hailing from Yellow 

 Springs, O., in treating of " the pawpaw," jDage 262, observes, " We do not 

 remember to have seen, in book, pamphlet, or newspaper, the mention of its 

 name, except in technical botanical treatises," &c. If he will refer to the first 

 Geological Report of Ohio, page 69, he will find that Dr. Kirtland, one of the
