the purpose of supplying soft water for 

 the plants, I have placed a slate cistern 

 at one end of the pit, in order to collect 

 the rain water from the roof. The soil, 

 if permitted to come in contact with the 

 iron troughs, would, of necessity, be-

 roots of any plant: with a view to ob-

 the soil which rests upon it may be 

 more regularly heated. The other ad- 

 vantage and conveniences of this pit 

 will be apparent from the above plan 

 and section without further remark.'' —
