304 Different Modes of Budding. 



below the level of the bottom of the boiler. It being understood 

 that a given number of superficial feet of tube will throw off a 

 certain quantity of cubic feet of hot air per minute, it can easily 

 be ascertained, by the admeasurement of the house, and the 

 quantity of glass in it, what quantity of tubing is required for it. 



I need not enlarge upon the efficiency and economy of my 

 own plan of warming, as you will be a competent judge of its 

 qualities by my description of it. It certainly has a decided 

 superiority, in every respect, over the common mode of heating 

 by flues, and particularly in retaining the required temperature 

 with a small consumption of fuel, and very trifling attention. 

 Boiling water is much to be preferred to steam heat. My own 

 green-house, in which the apparatus is constructed, loses but a 

 few degrees of heat by allowing the fire to go out for six or eight 

 hours in the night. A short time is sufficient to make the water 

 boil again, when it expands and displaces the cold water in the 

 tubes, which are immediately supplied with hot water from the 

 boiler, the cold water retiring through the expansion tube down 

 the returning tube, whence it is heated and again projected for- 

 ward ; thus keeping up a continued circulation of hot water 

 through the tubes for a considerable time even after the fire has 

 been allowed to die out. 



This apparatus can be applied, with the best effect, to horti- 

 cultural and public buildings of every description, mansions, 

 offices, warehouses, drying-rooms, &c. &c. ; and, as the tubes 

 have no connection with the fire, not a particle of burned air is 

 communicated by them to the room in which they act.

Art. III. On the different Modes of Budding ; and qf Herbaceous, 

 or Summer, Grafting. 



The following: article we have translated, with some additions 

 and variations, from V Horticidteur Beige ,- and we present it to 

 our readers as more complete than any article which has hitherto 

 appeared on budding and herbaceous grafting in the English 

 language. We have given the French names of the different 

 kinds both of budding and grafting ; not only because we think 

 the doing so will be useful to gardeners who visit the Continent, 

 or read French books on gardening, but because many of the 

 terms are not translated literally. For example, the French 

 apply the word greffe (graft) as a generic term including both 

 grafting and budding; whereas the English, and also the Ger- 

 mans, use distinct words for these two kinds of operations, The 

 Germans use the word veredlung, ennobling or improving, as 

 including both grafting, propfen, and budding, ocurliren. In 

 English we have no gardening word to express the two oper- 

 ations, although the word insition might be used for this purpose.
