mences to deposit its eggs. Two generations of the small bark beetle 

 are produced in the course of the year, and consequently it increases at 

 a somewhat rapid rate where the conditions are favourable to its repro- 

 duction. The beetle has the greatest preference for trees that are in a 

 more or less unsatisfactory state of health, and, recognising this fact, 

 American cultivators recommend that when an orchard is badly infested

down in June and burned, it being, of course, important to perform this 

 operation before the beetles attain full development and escape. In- 

 festation of the trees by this pest is indicated by the ends of the young 

 shoots dying away and the shrivelling of the leaves ; and in the case of 

 trees in small plantations known to be infested, it will be advisable to 

 examine the branches and remove and burn all that are found to be 

 punctured. The attack of the beetle may possibly be warded off by 

 painting the wood with a paraffin emulsion, or some other winter dress- 

 ing, before the buds begin to swell ; but this method can only be re- 

 commended when a few trees have to be dealt with, and, speaking 

 generally, the pest can be kept in subjection by cutting off and burning 

 shoots seen to be infested.

 mushrooms, viz., an ordinary growth with another mushroom growing from the 

 top of it. Mr. Rendle's specimen is the largest of its kind we have ever seen is 

 each mushroom measured about four and a half inches across, and the two-storied 

 specimen attained a total height of eight and a half inches.

 a time to ascertain what would be most acceptable to him, we suggest 

 that he be presented with a sum in a purse, towards which each member 

 should contribute a guinea, asking him to use it as he and his family 

 should prefer." The suggestion is an exceedingly happy one, and 

 knowing the estimation in which Mr. D'ombrain is held by the members, 

 we are quite sure it will be readily accepted and acted upon. It is some- 

 what unfortunate there should not be sufficient time to take the steps 

 necessary to raise a testimonial that would bear a more direct relation to 

 the remarkable services that have been rendered by Mr. D'ombrain in 

 the cause of horticulture than is now possible. But we presume the 

 members of the Horticultural Club do not wish to limit the pleasure 

 inseparable from showing in a tangible form their appreciation of Mr. 

 D'ombrain's services, and of his invariable geniality and courtesy; but 

 rather that they will gladly welcome expressions of sympathy with the 

 movement from all who take an interest in floriculturists and horti- countries

IVombrain's services that have been so freely rendered during the past 

 half century is not now necessary, as he is well known to all as an active 

 and able worker. But his most conspicuous services have been the 

 founding of the National Rose Society and the Horticultural Club, and 

 the conduct of their affairs as honorary secretary from their foundation, 

 and these alone more than justify the steps that are being taken by Mr. 



Munro and Mr. Veitch with a view to enable those who appreciate Mr. value! 

 D'ombrain's work to give practical expression to their feelings on this N 

 auspicious occasion. c 



Variation in Ferns is a subject with which our able coadjutor, Mr. C. T. 

 Druery, F.L.S., V.M.H., is pre-eminently conversant, and has frequently dealt 

 with in our columns, consequently his discourse at the Horticultural Club <a 

 Tuesday next cannot fail to prove both interesting and instructive. Mr. Druery'i 

 lecture is on " Nature versus Culture in Fern Variation," and it will be illustrated 

 by Nature-prints by the late Colonel Jones, who was also a great authority up« 

 British ferns. 



The Eucalypti, or Gum Trees of Australia are now generally 



recognised, not only as the giants among trees, and as providing splendid timber, 

 but as possessing medicinal virtues of various kinds, but it is not so generally 

 known that such virtues are shared also by different species of tea tree vm\ 

 wattle. The flowers of the native pittosporum yield a jasmine-like scent by 

 distillation ; and the boronia and other rutaceous plants abound in volatile oik

Calandrinia Tweed! is a new and interesting plant now flowering for the 

 first time in England, in the Alpine House at the Royal Gardens, Kew. The 

 foliage is stout and deep green, and the habit of the plant is dwarf; a specimen 

 might readily be mistaken for a statice when not in flower. The flowers are about 

 two to two and a half inches across, and of a soft salmon tinted flesh colour ; 

 they :ir e starry, and have eight segments. The species is from California, and 

 sent to Kew by Mr. Johnson, Oregon ; it is said to be hardy, and the authorities 

 are testing its capabilities as a hardy plant in the rockery. Should it resist our 

 damp winters it is a plant that lovers of hardy and rockery plants will soon desire 

 to possess. The genus Calandrinia belongs to the natural order Portulacese.
