Carnations from Seed. By W. A. Watts (Garden, p. 211; 

 27/9/1902). — An article showing the valuable experience of an amatsur 

 in Carnation-growing. The following note is interesting : — " This raising 

 of plants from seed may seem a long process, but patience is everything 

 in gardening, and the reward will come when you see your plants show- 

 ing a mass of buds, and you eagerly scan them every morning and 

 criticise the flowers as they open. Now, one word of warning — you 

 must not expect too much ; there will be many that are not worth 

 keeping, owing to the flowers being badly formed, and there will be a 

 certain percentage of singles ; but amongst the rest there should be, if 

 the seed has been good, a nice lot of plants that you can layer for pro- 

 ducing plants to bloom the next season, and these layers you will find 

 are mostly stronger, and naturally more likely to suit your climate and 

 soil, than plants you can procure elsewhere." — E. T. C. 



Carrot Fly. By F. H. Chittenden ( U.S.A. Dep. Agr., Div. of Entom,, 

 Bull. 33, pp. 26-32 ; one figure). — This well-known insect (Psila rosce y 

 Fab.) is fully described and the injuries done to the Carrot noted. As 

 means of controlling the attacks the following are recommended : — (1) 

 kerosene emulsion (one part to ten of water) sprayed along the rows 

 weekly, from the time the roots begin to form and especially after thinning, 

 until the end of June ; (2) late sowing ; (3) rotation of crops ; (4) 

 destruction of insects in stored crops. 



The fly is reported to have attacked Celery as well as Carrot, a fact 

 which must taken into account in planning rotations. — F. J. C. 



Cassava, Report on. By R. Thomson (Bull. Bot. Dep. Jam. ix. r 

 Tt. 6, p. 81, and Pt. 7, p. 97). — Deals with culture, expenses, chemical 

 analysis (72 per cent, being starch of dry root and 3 per cent, sugar), 

 and comparisons with other roots and the manufacture of starch sugar. 

 Cassava, its cultivation in Florida and advantages in Jamaica. — G. II. 



Cattleya hybrida picta. (A. Pericat in Amer. Gard. xxiii. 

 pp. 306, 307, fig. 70; 10/5/1902).— It is interesting to know that this 

 plant is still in the land of the living, as it has been "lost to sight " for 

 many years, though it has always been "to memory dear" as the first 

 hybrid Cattleya raised by hand. It was raised by Dominy as far back 

 as 1859, and was probably a hybrid between C. guttata and C. Loddigesii. 

 Its sepals and petals are light greon, spotted with purple ; petals margined 

 with rose ; lip violet-purple, with white margin and yellow throat. It is 

 now in the collection of Mrs. G. B. Wilson, of Philadelphia. — C. C. H. 



Cattleya x Leucothoe (E. (). Orpet in Amer. Gard. \\\\\. p. 513: 

 i) 8 1902). — A new hybrid raised at S. Lancaster, Mass., out of C~ 

 granulosa by C. Walkeriana. Flowers light rosy-lilac, dotted v.ith crimson ; 

 lip crimson, with white lines. — C. C. II. 



Cattleya x Nepthys (E. (). Orpet in Amer. Gard. xxiii. p. 483, 

 26 7/1902).— A new hybrid raised at S. Lancaster, Mass., between C. 

 granulosa Schoficldiana % and C. supcrba, the former being dominant in
