At Bicton, the paths of the pine stoves are dehiged 

 with water, many times daily, in clear fervid weather. 

 They have perforated pipes, so constructed all round 

 the fruiting pine structure, that they can turn the 

 water on the whole or part, at back or front of the 

 structure, and both ends, at any desired time. It is 

 so constructed that they can turn on a very strong 

 power of water, and entirely deluge the whole struc- 

 ture in a few minutes, or they can ease it down to the 

 softest dribble, or in single and very slow drops ; and 

 this is at all times in full command. Copper pipes 

 are employed, placed in union joints, by which means, 

 with a single turn, the water can be made to spray 

 over the whole surface of the walls of the structure, 

 or the paths or the heating apparatus, either in part 

 or over the whole. 



If tan or other fermenting mass is within the stove, 

 this yields much moisture, but nothing nearly suffi- 

 cient ; and to increase the amount, the paths should 

 be deluged with water at least twice daily ; viz., about 

 the middle of the day, and at night when about to 

 shut up. At this latter time, also, the plants may 

 be syringed. 



If the tank system of heating the stove be adopted, 

 I another aid to keeping the atmosphere moist may be 

 i adopted, as suggested by Mr. E. Errington, the very 

 ' able gardener of Sir P. Egerton, Bart., at Oulton 

 Park. He observes upon this point, that in applying
