to let it appear through an opening left in the folds of the 

 bass, as at -p q, Jig. 9. It will be seen that the graft, by 

 this method, only bears two superior buds ; and that the third, 

 left on the lower part, forms the shield, and should be freed 

 from wood, according to the species and to custom. The 

 operations are the same; but the latter plan offers more chances 

 for the success of the bud, without interfering with the graft. 

 The results of a great number of trials of the new methods 

 are given by M. Vergnaud Romagny. I will not take up 

 more of your valuable space than to state that he considers 

 the result to be more than a gain of one half the time 

 usually required by the ordinary mode of grafting; and that 

 these sort of grafts resist the effect of cold. Various kinds of 

 delicate roses resisted an intense cold, while some by the old 

 method, even of two or three years, perished. 



Would steam injure fruit trees, if applied by the machine 

 used for destroying bugs ; and would it not destroy the A^phis

Sir, 



A NEARER approach than has hitherto been made to per- 

 fection, in all the requisites for good labelling, I suppose 

 myself to have made, and am about briefly to describe. The 

 first object to be aimed at, in a good label, is immutability 

 by the effects of climate and seasons ; the next, quantity of 

 information, and perspicuity in the mode of conveying it. 



Labels have hitherto been made either of lead, iron, woodj 

 or pottery. Lead bends, and is liable to be stolen ; iron rusts, 

 and destroys the paint ; wood rots ; and pottery moulders, 

 unless so hard as not to receive paint, and is always clumsy. 



Common paint has been used for the nomenclature of all 

 but the latter, which have, I believe, been stamped. 



The labels I propose are composed partly of iron, partly of 

 copper and enamel. Start not, reader, nor exclaim " Expense ! " 

 for I purpose to show that the original and entire cost of this 

 will not be greater than the sum expended in two or three 

 years renewing the present defective ones. To proceed : my 

 label consists of a cast-iron ring, elongated at one side into a 

 prong, to stick into the earth ; cast into the centre of which 

 is a disk of copper, not more than one twentieth of an inch in
