226 Cucumber or Melon Pit 



diameter or height than the glass case will conveniently con- 

 tain. If a space of one foot be allowed between the trellis and 

 the glass, it will be sufficient ; and, if the case were constructed 

 in two parts, it would be more convenient in putting up and 

 taking down, and would also give more room and freedom 

 in the management of the tree and fruit. 



Strong young vines, or other desirable fruit, planted on 

 purpose for this mode of culture, would answer well ; and, as I 

 have calculated the expense of one at about 2/. IO5., a dozen of 

 such cases, for grapes or other fruit, would cost much less 

 than a house, which would perhaps not yield more than 

 these portable frames. Strawberries on a conical stage would, 

 no doubt, succeed well in this way : and, indeed, I am so tho- 

 roughly convinced of the utility of such erections, that I would 

 even advise a row of them to be heated by hot water. 



I have no convenience at present to try this scheme ; bat I 

 shall prepare to do so as soon as possible, and in the mean- 

 time should be gliad to find myself preceded in the project by 

 some of your readers. Yours, &c.

Art. XVII. Description of a Cucumber or Melon Pit xvitk 

 bevelled hollow Walls ; isoith a Suggestion as to the Use of 

 these Walls for other Purposes, in Gardening and Cottage 

 Building. By Mr. Alfred Kendall, C.M.H.S., Gar- 

 dener to Lady Palmer, Wanlip Hall, Leicestershire. 



Sir, 



I send you herewith a section {Jig. 67.), and also a model 

 of two forcing-pits, built with bevelled hollow walls ; and, if 

 you think the following remarks on them deserving a place 

 in the Gardener's Magazine, they are very much at your 

 service. 



The peculiarities of these pits are the bevelling of the walls, 

 by which they may be made of any height without piers, and 

 with no more material than what is contained in a common 

 hollow nine-inch wall ; and the facility with which, by means 

 of these hollow walls, a dry heat is obtained from moist dung. 

 In other particulars these pits are not materially different from 

 some plans which have already appeared in your Enajclopcedia 

 and in the Gardener's Magazine. 



Supposing a cross section through two of these pits to be 

 examined, it will present the back wall hollow, 12 in. thick at
