Description of a Pine Pit, $c. 221 



Yorkshire-stone covering over the flue is a great saving ; it is 

 less costly than glass, and as the part that it covers requires 

 no heating, by using it, instead of glass, the lights are reduced 

 to a more convenient length. If there were no stone, the 

 lights must be in two lengths, and the rafters would neces- 

 sarily be considerably larger, so that there would be more 

 shade on the centre of the bed, if the flue was within the 

 glass. I always cover the lights with mats in cold weather. 



The Pit is constructed in two divisions, in order to keep 

 up a succession of fruit. 



I am, Sir, 

 Your obedient humble servant, 



Putney Hill, THOMAS ScOTT. 



July 1, 1822.

 lators, the latter seen through the lights.

3. Plan of walls, furnaces, flues, and stoke hole. 



The piers shewn in this plan are to support the 

 stone slabs which cover the flues, and the inter- 

 mediate spaces are to admit the heat from the 

 flue. The cross lines on the back wall mark 

 the situation of the ventilators.
