Cattleya MagTieana. By Ch. Maron (Le Jard.). — This splendid 

 novelty is one of the most beautiful of the species : it was produced by 

 crossing a superior variety of Cattleya guttata Leopoldi with C. Massaiana, 

 one of the best of the Hardyana group. The height of the plant when in 

 bloom is about 20 inches, and of the pseudo-bulbs 10 inches. The leaves 

 are about 8 in. x 2\ in. They are thick, tough, and of a beautiful dark 

 green colour. The floral stem has four branches, and consequently five 

 flowers. These when fully open are of a remarkable size ; indeed, the 

 largest known diameter is 3| inches. The sepals are firm and cohesive, 

 the upper one being remarkably erect, and they are of a plain ruby colour. 

 The side petals are very wide and firm, with wavy edges and of an intense 

 dark ruby colour. The lip, perfectly formed, very large, well opened, and 

 with large curves, is of an intense ruby colour, which is deeper round the 

 curves. The bottom of the orifice as well as its under side has a fawn- 

 tinted shade. The rostellum, which is situated in front of the orifice of 

 the labellum, is very large, and looks like a decorated Almond. 



The plant requires no special care in cultivation. It should be kept 

 in a good temperate house with the other Cattleyas.

Cedar Pencils. By P. Hariot (Le Jard. Oct. 5, 1902, p. 289). 

 Pencils "made in Germany " excel all over the world. It seems that 

 Messrs. Faber. the great German makers, have planted a grove of 

 Junip&nts virginiana (the Red Cedar) in Germany which gives them an 

 advantage over importers of the wood. This writer asks, Why not in 

 England ? But it has perhaps been proved a failure. Indeed it is said 

 that the most approved kind for pencils, J. bcrmudiana, is too tender to 

 thrive in England.— C. W. D. 



Celery. By C. A. Keffer {University of Tennessee Record, January 

 1903, p. 58). — In Tennessee, where it is apt to suffer from drought, Celery 

 requires very heavy manuring and careful cultivation, under which 

 conditions it is ready for use in about ten weeks from planting. 



No advantage is gained by adding lime or acid-phosphate to the 

 stable manure used. — C. H. C. 



Cherry Disease, A New. By Paul Noel (Le Jard.). — M, Corboz, of 

 Ancleins, has discovered a curious new Cherry disease, which is caused by 

 a parasitic fungus, Gnomonia ery thro stoma. From the beginning of 

 summer the leaves begin turning yellow in places, then the stems turn 

 brown, and before autumn the leaves gradually dry up, rolling up from 

 the edges and turning towards the ground. These prematurely dead 

 leaves do not fall with the others at the end of autumn ; they remain on 

 the tree during the whole of the winter and the following spring. At 

 this season they are covered with little black spots, which are easily seen 

 by the unaided eye. These are the fructifications of the Gnomonia 

 eryihro8toma. M. Corboz says the disease may be easily subdued by a 

 very simple method, which is indicated by the progress of the disease
