49. Upon a Mode of covering the nahed Branches of Fruit Trees 

 tvith new Wood. By Samuel Spyvee Street, Esq., of Penryn, 

 Cornwall. 



Wall and espalier trees often become naked for a foot or 

 two on each side of the main stem; but by ringing the lateral 

 branches at 6 or 8 in. distance from the main stem, young 

 shoots will be thrown out between the ring and the stem, 

 which may be trained over the naked parts at pleasure.

 Varieties of Spring Crocuses, cultivated in the Garden of the 

 Horticultural Society. By Joseph Sabine, Esq. F.R.S. Secre-

 Kensington, in 1818. This collection included a very ex-

 quarters, to which additions have since been made. 



Linnaeus, in 1753, had only one species of Crocus, C. 

 sativus, considering the autumnal or saffron crocus ( C. offici- 

 nalis), and the spring crocus (C vernus), as varieties. Will- 

 denow, in 1797, made Linnaeus's two varieties species, calling 

 the autumnal crocus C. sativus, and the spring one C. vernus. 

 The crocus has been found wild in the southern parts of 

 Europe, and in the temperate regions of Asia; and botanical 

 travellers " have proved the existence of many kinds of 

 Crocus in a wild state." Most of these remain to be described, 

 and a monograph is preparing by M. Gay of the garden of
