growth they drop to the ground and bury themselves between 3 and 4 

 inches from the surface. The most certain way of destroying this insect 

 is therefore to remove the soil under the trees to the depth of 3 or 4 

 inches, and burn it or bury it deeply. If this operation is carried out 

 properly there should be no sawflies next year to lay their eggs on the 

 leaves unless some come from a neighbour's garden. To destroy the 

 grubs, the leaves should be sprayed with paraffin emulsion or ' Paris 

 green ' (Blundell's paste is the best), 1 oz. kept well mixed in 12 gallons 

 of water. This should be applied in as fine a spray as possible, and the 

 leaves not wetted so that they drip." 



Stocks Dying. — Some stocks in a very unhealthy condition, with 

 withered leaves and drooping flowers, were shown from Canonbridge, N.B. 

 Upon these Mr. Saunders reports : " I find in the soil in which the 

 stocks were growing a number of small worms belonging to the family 

 EnchytrceidcB, which would account for the condition of the plant, as 

 these worms are very injurious to the roots of many plants. They may 

 be killed by soaking the soil with lime-water. Plants in pots which are 

 infested by these worms should be very carefully handled when on the 

 potting-bench, to prevent any of the soil remaining on the bench, which 

 might contaminate any fresh soil which might be there or placed there 

 afterwards. The infested soil should be burnt or baked, or spread where 

 poultry and other birds can scratch it over and pick out the worms." 



Diseased Leaves of Sikkim Rhododendron. — Mr. Saunders reported 

 that these were evidently attacked by fungus, and they were referred to 

 Mr. Giissow for examination. 



Double Peach. — Mr. Worsdell showed a double fruit from a purple- 

 leaved peach which had been growing in the open in a dry place. Both 

 parts of the fruit had spLt. Mr. Gordon observed that the splitting of 

 peaches appeared often to be the result of a sudden supply of water after 

 a season of comparative drought. Other members remarked that the 

 splitting of the fruit was usually accompanied by the imperfect formation 

 of the stone. Mr. Worsley said that since giving a dressing of lime to 

 his peach-trees he found that the stones were always well formed, whereas 

 before the stones were frequently imperfect. 



Remarkable Abundance of Lenticels on Apples. — Mr. Saunders drew 

 attention to a shoot of apple on which the lenticels were remarkably 

 numerous and of large size. The trees which showed this peculiarity 

 were growing in an orchard which had borne little fruit, but had produced 

 much wood. - 



Brachystelma Barberies.— Mr. F. W. Moore, of the Royal Botanic 

 Gardens, Glasnevin, sent a specimen of this remarkable asclepiad from 

 South Africa. 



Scilla hcemorrhoidalis. — Mr. Worsley showed this and the following 

 plants from Isleworth. This plant is a native of the Grand Canary, and 

 is remarkable for its ornamental fruits. 



Hymenocallis senegaiubica. — This is the only Old World member of 

 its genus, and appears to be much more hardy than the American forms. 



Pellionia Daveauana. — A plant remarkably like a Begonia, but 

 belonging to the Urticacece. Well figured as Begonia Daveauana in 

 " Rev. Hort." 1880, 290.
