or, what would be incomparably preferable, stamped into the unburnt brick 

 with types. Or sunk panels might be formed in the ends of the bricks to co n- 

 tain a slip of wood with a bit of glass glazed over it, in Mr. Stuart Murray's 

 manner, so often recommended. Such bricks are now making for us by 

 Mr. Peake of Tunstall, and we shall take an early opportunity of sending 

 one to Mr. Massie for Mr. Allardyce. In the mean time, we should be glad 

 to know from the latter gentleman, from Mr. Peake, or from any other brick 

 or tile manufacturer, what would be the charge for impressing with types 

 1000 bricks, four words on the end of each brick (generic and specific- 

 name, native country, and year of introduction), the words averaging six 

 letters each, and all bricks on which the words are misspelt to be paid for as 

 common building bricks. The size of the letters of the type to be exactly 

 double that of the letters in the words Gardener's Magazine on our cover - T

Brick tallies, named in this way, we should think, would be the cheapest 

 and most durable of all tallies, and, according to our taste, they would look- 

 better than any other in a botanic garden or in private collections. Small 

 iron or wooden tallies placed at the roots of large old trees, as at Kew and 

 Syon, certainly do not look so well as brick tallies would. With numbers, 

 these tallies might be used by nurserymen. We should wish therefore to 

 know the price of 1000 bricks, numbered from 1 to 1000. — Cond. 



Transmitting-heat Wall. — The Rev. J. A. H. Grubbe of Stanton St, 

 Bernard, Wiltshire, has taken out a patent for a wall so named. The 

 intention is to erect thin partitions in gardens as substitutes for walls, against 

 which fruit trees may be trained, and through which the warmth of the sun 

 may, by reason of their thinness, be transmitted, which will greatly promote 

 the ripening of the fruit, and improve its flavour. The material proposed 

 to be employed for constructing these walls or partitions, is slate of the 

 ordinary quality, in slabs of the kind usually applied to the roofing of 

 houses. Iron frames are proposed to be prepared for the reception of the 

 slates, like the frames of windows [with holes in both sides for inserting 

 wires to serve as a trellis], and the slates being cut to proper shapes and 

 dimensions, may be secured in the rebates of the frame, by putty, in the 

 same way as glass. These frames are to be from 6 to 8 ft. wide, and of a 

 suitable height, and may be joined together side by side, by rebates or 

 flenges, and held fast by screws, bolts, pins, or staples, or in any way that 

 may be found desirable to secure them firmly. Temporary blocks of stone 

 may be placed along the ground to support the partitions, with cross pieces
