means of forcing, these being placed over the plants or subject to be 
forced, such as Rhubarb, Asparagus or Seakale and fermenting ma-

ornamental shrubs can stand as hard forcing as most plants, but some 
of the bulbous subjects, as Darwin Tulips and varieties of Daffodils, 
go blind if forced hard.

a yard full of frames, which can be used over hotbeds or simply as cold 
frames, and for growing on semi-hardy plants or for hardening off 
bedding plants. For these purposes they are handy and well* suited. 
The illustration above shows a type of brick frame with sliding sashes 
Duilt against a warm greenhouse, there being rectangular spaces under 
the greenhouse wall where the heat can come through to these pits, or a 
line of hot water pipes could be run in behind very simply. The making 
of cement frames has been treated of in previous editions of this 
Annual, notably the 1915 edition. 
Fountains, Electric. — Little table fountains are much more fre- 
quently seen and used than formerly. They may be had in a large 
number of different forms and patterns, for the table, the stage, the 
platform, the vestibule, the lobby. They are self operating, the construc- 
tion being extremely simple. Their operation consists of a specially 
constructed motor attached to a centrifugal pump; the latter placed 
in the interior of a basin. The pump gets the water directly from the
