two lumdi-cd aiul eighty-six beans. Two of the stems were 

 5 ft. hi<j;h, and the rest from 2 to 4 ft. A sort of protuberance 

 was formed above the roots, which was occasioned by the 

 phmt having been broken, or bruised, when quite young.

Though tlie country in (jucstion is now generally culti- 

 vated, it may be still seen that a foi"cst originally covered 

 the whole. Loam is the principal soil, in which the various 

 trees of those forests flourish luxuriantly ; and whilst some are 

 clothed with leaves and flowers, others appear to be in a 

 state of rest. M. Beyrich mentions the singular circum- 

 stance, that, when one of those original forests is hewn down 

 and burnt, the succeeding vegetation consists of quite dif- 

 ferent kinds of plants from what formerly existed ; but he does 

 not attempt to account for this occurrence.

M. Otto proved, on M. Host's authorit}', that maro- 

 schino (a kind of cherry brandy) is made from the fruit of 

 Priinus bis-florens (twice-flowering plum), which grows wild 

 in the neighbourhood of Zai'a, and not, as it was generally 

 believed, from Prunus Mahdlch (now Cerasu.s Mahdlcb). 

 M. Lenne gave an account of the improvement of the 

 National Nursery, which contains 'j40 sorts of apples, 236 of 

 pears, 98 of plums, and 100 sorts of cherries; and promised 

 to give a more particular account at a future time.

When the bulbs begin to grow, more water is given them, 

 and, if recjuired, larger pots. If they flower before the leaves 

 appear, they must be repotted after they have ceased flower- 

 ing; but no roots should be cut ofl", except those which are 

 dry or rotten. The size of the pots depends entirely on the 

 size and growth of the bulbs ; and some of them may 

 remain several years in the same jiot. Suflicient moisture 

 can be supplied to the roots, by putting the jiols in a pan, 

 filled occasionally with water, which gives the bulbs more 

 strength, and is more likely to save it from rotting, than 

 when the water is put, as usual, on the toji. The soil in 

 which ihey are planted is composed of one part of loam, 

 which does not contain oxide of iron, and two parts of leaf 

 mould. Small stones must be put in the bottom of the pot, 

 to facilitate the jiassage of the water.
