674. Eight-foot lights, when placed at an angle of 30° or 35°, as in fig, 7, 

 make an excellent house for sheltering bedding-out plants, and, with suitable 

 heating apparatus, would form an admirable cucumber or melon-pit. The- 

 only arrangement ne- 

 cessary would be to 

 dig out the soil three 

 feet below the ground- 

 level, to give head- 

 room ; then lay down 

 half a foot of rubble, 

 for drainage, and fill 

 up to the surface with 

 good sandy loam, 

 leaving a central 



path three feet wide. If this border is made outside as well as in, very 

 good grapes may be grown while giving shelter to the bedding-plants, by 

 using the ventilators adapted for wintering the vines, and admitting them 

 after they have ripened their wood outside. Or these houses may be- 

 employed for small greenhouses by placing them on side-walls from two to 

 three feet high, instead of sinking for a path, and placing flat stages on 

 each side over the pipes on which to stand the pots, &c. ; and for the pot- 

 culture of strawberries this arrangement answers extremely well. Peach.

and other trees in pots may be grown when the stages are dispensed with^ 

 and thus a very cheap and efiicient orchard-house on a small scale may 

 be formed. Ten or 12-foot lights placed at an angle of 35° give a favour- 

 able form of pine-pit : the one gives a width of 16, and the other of !&• 

 feet ; and if a sunk walk of three feet wide occupy the centre, and a foofe
