In order to study the effect, in point of colours, which this ericetum will 
have in every month of the year, we recommend the reader of leisure, and 
more especially the young gardener, to make 12 copies of fig. 886., and then 
to look at App. I. (p.1088.), and observe the sorts of heath which will be in 
flower in each month of the year, their colours, and their heights. Then let 
him take the copy of the plan of the ericetum for January; and, as he will 
find by the list, App. IL, that there will be only two sorts in flower during 
that month, viz. Gypsocallis cérnea and G. c. herbacea, both of which have 
pink flowers ; let him colour with pink. all the beds indicated to be planted 
with that sort, colouring all the other beds green. This will give 8 red 
beds and 65 green ones for the month of January. To indicate the height 
which the plants in each bed are supposed to attain, the height 
of each sort, as indicated in the list, may be taken from the § 
scale; and each bed drawn in isometrical projection, as shown 
in fig. 887., which is supposed to represent bed No. 21., intended 
to be planted with Gypsocallis mediterranea, a species estimated to grow to the 
height of 4 ft. Whether the operation of colouring is performed on a ground 
plan, such as fig. 886., or on an isometrical view to show the height, prepared 
after the manner described, the colouring ought to be applied from the list
