surface loam, and half-rotten hog dung, of each equal quanti- 

 ties, kept as rough as possible, in which state it should be ap- 

 plied on all occasions. The mixture should never be used 

 when more than twelve months old. It may be here observed, 

 that no pine plant should be checked in its progress ; for the 

 consequence of checking is always a premature and weak pro- 

 duction of fruit." 



This last observation deserves the particular attention of 

 gardeners, as it applies not only to pines, but to the whole 

 class or division of vegetables termed by botanists Monocoty- 

 ledones, including palms, bulbs, and grasses. It does not 

 apply in any thing like the same degree to Dicotyledones. 



20. An Account of the Calville Rouge de Micoud, a new Variety 

 of Apple. By M. Andre Thouin, Foreign Member of the Hor- 

 ticultural Society. (Gard. Mag. 226.) Read July 15. 1823. 



This apple tree was raised from seed about forty years ago, 

 on the banks of the Loire. Its first season of flowering gene- 

 rally takes place in April, at the same time as the greater part 

 of the other varieties of apples ; the second is in June. The 

 tree then ceases for a time to produce flowers ; the third and 

 succeeding flowerings take place in August, September, Octo- 

 ber, and November, when they are stopped by the severity of 

 the frost. It is necessary to remark, that the last flowerings 

 are much less abundant than the two first, and the fruit which 

 they produce is small, and imperfectly ripened. 



The fruit of the first crop is in form depressed spherical : 

 near three inches in diameter across the centre of the fruit, but 

 not exceeding two thirds of that measure in its section from 

 the stalk to the eye. Its maturity commences about the mid- 

 dle of July, and continues with little interruption till Novem- 

 ber. The fruits of the April flowering ripen mostly in August, 

 and are usually eaten during the harvest. Those of the second 

 flowering succeed the first, and may be brought to table till 

 the end of October ; these are quite as good as the first, but 

 are not bigger than a hen's egg. The fruit of the later flower- 

 ings are not bigger than a small pomme d'api ; neverthe- 

 less, when they are stopped in their growth by the frost, they 

 may be placed in the fruit-room, where they ripen very well, 

 and keep till November. 



It has been called the Calville Rouge de Micoud, in honour 

 of the Baroness de Micoud, on whose estate it was raised.
