excellent quality, and wants far less attention than was re- 

 quired by my former method ; for the frame-work renders 

 hand-glasses, or any other cover, unnecessary. Care should 

 be taken to lay the dung in such a manner that the top may 

 be partly, or wholly taken off, at any time, for the purpose 

 of gathering, or examination, without disturbing the sides. 

 That this is a superior method of forcing the Rheum Hybri- 

 dum, this year's experience has satisfied me ; but still the 

 forcing by pots will answer very well for any of the smaller 

 growing species. 



I have never found any difference between using dung 

 fresh from the stable, and that which had undergone fermen- 

 tation, provided it was not suffered to heat violently after its 

 application to the frame. I do not permit the internal heat 

 of the hollow space, above the plants, to rise above 60° of 

 Fahrenheit's scale, between 55° and 60° being the proper 

 medium. If it should become too hot, that may easily be 

 corrected by making two or three large holes through the 

 top of the dung into the space above mentioned. When 

 pots are used, if the dung is found to be heating too much, 

 the only method is to turn the whole over, and this should 

 be particularly attended to, as the shoots rise quicker than 

 when under the frame, and are sooner scalded than those of 

 sea-kale. 



To those who dislike the trouble of either frames or pots, 

 it may be useful to know that Rhubarb will come in much 

 quicker, by being covered about six inches thick, with light 

 litter ; care should be taken, in putting it on, and removing 

 it, that no injury be done to the plants.
