Caladenia gemmata. By R. A. R. (Orch. Bev. Aug. 1903, 

 p. 240). — Interesting particulars are here given of this blue, terrestrial, 

 Australian species. — H. J. C. 



Calanthes, The. By F. W. Thurgood (Gard. p. 321 ; 7/11/03).— 

 These are among the most beautiful Orchids, and are divided into two 

 sections, evergreen and deciduous, the latter being the more useful for 

 decorative purposes, and in consequence more largely grown. This 

 article gives a list of the deciduous species and hybrids, with full descrip- 

 tion. The methods of culture are also detailed at length. — E. T. C. 



Calothamnus rupestris. By Sir J. D. Hooker (Bot. Mag. tab. 

 7906). — Nat. ord. Myrtacece, tribe Leptospermece. Native of Western 

 Australia. The genus consists of 22 species, all restricted to S.-W. 

 Australia. It is a robust evergreen shrub, 7-8 feet high. Leaves \ inch 

 long, rigid, acute and pine-like. Flowers crimson, H inch long, petals 

 scale-like, but the stamens, forming the most conspicuous part of the 

 flower, are connate in four flattened clusters, with many yellow anthers.

Campanula pulla (Gard. p. 440; 27/6/03). — Among the neatest 

 as well as the most free-flowering of the dwarf Harebells is Campanula 

 pulla. In some districts difficulty is experienced with its cultivation, but 

 it usually grows and flowers freely if left alone. It appreciates a rich,, 

 light soil, and a fairly moist position, and if not kept to the rock-garden 

 its whereabouts should be well marked, as scarcely any evidence of the 

 plant is left during the winter. It must not be subjected to annual 

 division and transplanting. — E. T. C. 



Campanula Vidalii. By S. W. Fitzherbert (Gard. p. 297; 2/5/03), 

 — This Campanula is entirely distinct from the rest of the genus, and 

 although a handsome plant, is rarely met with. It was discovered by 

 Captain Vidal, R.N., in a small island near Flores in the Azores in 1851, 

 so that it has been in cultivation for more than fifty years. It is of 

 shrubby habit, forming a woody stem 9 inches to 1 foot high, which at 

 that distance from the ground throws out numerous branches, some of 

 which become elongated into flower-spikes. It cannot be left with 

 impunity in the open during winter, and should therefore be given glass, 

 shelter.-i?. T. C. 



Campylocentrum, The Genus (Orch. Bev. Aug. 1903, p. 245).— 

 Description and interesting particulars of some eighteen species of this 

 genus are given. As many of the species have been previously included 

 under other generic headings, the classification here given will be most 

 serviceable. — H. J. C. 



Cane Syrup, The Manufacture of. By H. H. Harrington (U.S.A. 

 Exp. Stn. Texas, Bull. 68, July 1903 ; illustrated).— The object of this 

 bulletin is to encourage the small farmer to manufacture Cane syrup, 

 either for his own use or to supply a local market. 



A fair grade of syrup can be made with a very simple and primitive 

 outfit, consisting of a three-roller horse mill for grinding the cane, and
