resting upon bricks laid on the ground. It will be seen that the space 

 enclosed in this little hot-house, and the easy system of ventilation, allow 

 the temperature to be elevated or depressed at will. Moreover, by its

 ground. Vines cultivated in an open garden-bed, or, better still, at the 

 foot of a well-exposed wall, and conducted in a unilateral horizontal 

 position, would be best suited to this kind of shelter. 



A branch of vine detached from the wall, and bent down towards the 

 soil, could also be forced in this way. 



Vines cultivated with long canes, and introduced under this simple 

 forcing-frame, would produce an abundance of fine fruit. Lastly, the 

 intelligent gardener would be able, in many other ways, to make use of 

 this simple construction to obtain the finest and most savory of all fruits.

 our hot summer's sun on these ground-vineries. — Ed.] 



CULTURE OF FERNS FROM THE SPORE. 



At the beginning of March, select a warm corner of the side stage of the 

 greenhouse ; place in a board two feet square ; then break small a quantit}' 

 of crocks, and cover the board to the depth of half an inch ; chop up very 

 fine a little sphagnum-moss, and cover the crocks ; next sift through a fine 

 sieve a quantity of sandy peat, with a small proportion of fresh loam ; then 

 mix up with a quantity of silver sand equal to both ; press the moss level, 

 and lay this compost on an inch deep ; and, when done, slightly smooth 

 and press lightly over the surface ; then give a slight watering out of a 

 fine rose, and, when the water has subsided, sprinkle on the spores pretty
