June 1910). — An industry which has made great strides of late years at 

 Hyeres is the raising of pahns for export to other parts of Europe, it 

 having been found that plants raised thus in the open air and in very 

 favourite at present seems to be the palm called Phoenix canarieiisis. 

 under glass in the North. Among the varieties thus raised the 

 favourite at present seems to be the palm called Phoenix canariensis. 

 It was first noticed in the gardens of Baron Vigier at Nice, to whom 

 it had been supplied with other seedlings by Messrs. Linden of Gand, 

 and was raised originally from seed they had imported from the Canaries, 

 whence the name, " This article contains much information as to the 

 management of the plant in all its stages as grown at Hyeres, and 

 mentions that the demand for it is still larger than the supply, though 

 no fewer than 40,000 specimens are grown yearly at Hyeres.

Phosphorus in Fertilizers, Carriers of. By C. E. Tnorne 

 (U.S.A. Exp. Sin. Ohio, Giro. 93, April 1909). — Twenty years' experi- 

 ments indicate that acid phosphate (superphosphate) has been the most | 

 effective phosphatic manure for cereals, but that basic slag and bone- | 

 meal are better in acid soils for clover. Soil acidity may be counter- ; 

 acted with lime, and then superphosphate is the most effective phos- 

 phatic manure.-— F. J . C. 



Phymatidium tillandsioides {Die Gart., September 17, 1910, 

 p. 485).— Rarely seen in cultivation. It was first discovered in the 

 province Parona in Brazil as an epiphyte at an altitude of 600 metres, i 

 It resembles a narrow -leaved, small Tillandsia. The leaves are pale 

 green and numerous ; the flowers are in ten to twelve flowered racemes, 

 and white. It is of easy cultivation, grown in a shady position in 

 14° to 18° Cel. in a small pot or pan in Sphagnum. Phymatidium \ 

 flowers twice every year. — G. R. 



Pipe, Calabash, The South African. By D. Fairchild and 

 G. N. Collins (U.S.A. Dep. Agr., Bur. PI. Ind., Circ. 41, Dec. 

 1909 ; figs.). — Calabash pipes are made from the crooked necks of a I 

 large gourd (Lagenaria vulgaris), which have hitherto been exclusively | 

 imported from South Africa. Considering the low price paid for the 

 imported necks, there is no idea of any profitable industry being built 

 up by growing them in America, where calabash pipes are now becoming 

 fashionable. The writers suggest merely that the plant is an attractive 

 one in itself, and that the high price which the firished pipes fetch in 

 America is due to their pleasing variety of shape, which necessitates 

 hand labour — always an expensive item there — in lining and finishing f 

 them. It might therefore be amusing and profitable for a man to grow 

 and make his own pipes, which could be done in leisure moments even 

 by one unaccustomed to the use of tools. The processes of fitting 

 mouthpiece and lining to bowl are fully described. — M. L. H. j
