Fic. 640. LEAF OF DESFONTAINEA SPINOSA.

 Desfontainea— continued. 
easy cultivation. It thrives in either a peat or loam soil, 
but preferably the latter. Cuttings will root if inserted 
in either of the soils above named, with the addition of a 
little sand; a gentle heat would accelerate the rooting. 
It forms an admirable plant for greenhouse or conser- 
vatory decoration, and even when out of flower its pecu- 
liar Holly-like appearance is most attractive.

DESIGNS. The art of taking plans or Designs of 
objects should, according to Loudon, be considered as part 
of a gardener’s general education, since none who aspire 
to any degree of eminence in their profession, ought 
to be ignorant of the first principles of geometry 
and drawing. A Design of the whole or any part of a 
garden, as, for instance, a flower-bed, intended as a 
working plan, should, above all things, be accurately 
drawn. It is impossible to correctly transfer an intri- 
cate Design from paper to show itself in a given space 
on the yo unless the boundary of that space has 
been previously measured, and it, with all the arrange- 
ments of the enclosure, carefully prepared on an equal 
scale throughout. In the case of a garden, the full size 
being known, and the scale determined (as large a one 
as practicable being preferred), the positions of any per- 
manent features of the inside, such as large trees, glass . 
structures, &c., either those already existing, or others 
contemplated, should be marked, and the scale attached 
to the Design for reference. A plan of a flower-garden 
or carpet- bed should have the same rule of drawing 
to scale measurement applied, as the position and space 
to be occupied by different plants can be previously 
arranged, and the proportion of colours properly in- 
serted. A glance at this, when bedding time comes, 
will at once indicate the positions assigned to all the 
plants, and so prevent much confusion that would 
otherwise prevail. Intricate carpet-bedding Designs are 
often worked out by marking the lines with white sand; 
others may be shown with stakes or small pegs. Designs 
for glass structures vary according to the requirements 
of the plants for which they are intended; but each 
should show, in the same proportion, all the working 
details it is proposed to introduce. in
