Carnation and a 1 Sweet William ; ' also the Pink hybridus floribundus, 

 suggesting that it might be identical with the first hybrid known to 

 have been made artificially by Mr. Fairchild. See Joukn. R.H.S. xxiv. 

 p. 56. 



Sawdust. — In reply to an inquiry from Mr. Allen, Putney Hill, as to 

 whether this material can be utilised, the general opinion was that it is 

 worse than useless, but it becomes valuable if burnt. It was suggested 

 to burn it mixed with vegetable rubbish, then to sift the ashes and mix 

 them with sifted earth. This has been proved by experience to be a very 

 valuable top-dressing. 



Scots Pine diseased. — Specimens received from Mrs. Turner, Ightham, 

 were examined by Mr. Xewstead, who reported : — " The insect is Chermcs 

 pint, an aphis ; the white flocculent matter covers the adult apterous 

 female and her yellowish-brown pedunculated eggs. Soft-soap and 

 quassia is a very good insecticide for this pest ; but the paraffin emulsion 

 will give the best results if applied before the trees have made young 

 growths." 



I recommend the following recipes for summer (1) and winter appli- 

 cation (2) : — 



(1) For Aphida : 7 galls, soft water, 5 oz. soft-soap, 8 oz. quassia well 

 boiled and applied cold in dull weather with a " spray " syringe. (2) For 

 American blight, Sec. : J pint soft water, J oz. best white soap, 1 pint 

 paraffin. Dissolve the soap by boiling it in water ; add paraffin and churn 

 with a syringe for several minutes ; add nine times the quantity of warm 

 water and again churn with a syringe. This is to be applied to the bark 

 in winter with a stiff brush. 



Picea ajanensis. — Dr. Masters exhibited specimens sent by Mr. Moore, 

 of Glasnevin, shewing the apex of the yellow male flower occupied by bracts 

 and ovuliferous scales of the usual purple colour. The foliage leaves, 

 perular scales, and stamens were seen to be in continuous sequence, and 

 the bracts of the female portion were also continuous with the foliage 

 leaves. The ovules were not fully developed. 



Hybrid Clematis. — Dr. Masters also showed flowers of a hybrid 

 Clematis raised between C. coccinea, which has ovoid tubular scarlet 

 flowers, and C. lanuginosa, which bears much larger flat lavender- 

 coloured flowers.

Vegetable Products of West Indies.— Siv Daniel Morris, K.C.M.G., 

 gave an interesting account of the cultivation and introduction into the 

 English markets of new fruits now being raised. Thus, the Litchi has 

 been brought fresh from Trinidad ; its cultivation requires alternations of 

 bright sunshine and water, so that its success depends upon artificial 

 irrigation in the dry season. Mangos can now be also imported fresh, as 

 well as much-improved Smcoth Cayenne Pineapples, of the type grown 

 in St. Michael's, the average price being 4s. Bananas, usually imported 

 from Jamaica and Costa Rica, are now received from Barbados. The
