“ E. cerinthoides is spread more extensively over the Cape colony than 
any other species; it thrives best in the most exposed situations. 
“ The soils in which Nos. 1 and 4 are found, approach nearly to some of 
our bog soils, but not precisely so; so that, excepting Nos. 1 and 4 as 
above, no bog earth is wanting; it only serves to weaken the growth 
where a good sandy loam would strengthen it, and insure good flowering 
plants for years. Fire heat, and a long confined atmosphere and smoke, 
are injurious to Ericee ; fresh air ought to be admitted freely, for although 
the finest species come from a warm country, yet they withstand several 
degrees of frost. Some greenhouse species will bear some British winters ; 
always better if in a northern exposure.” ( Gard. Mag ., vol. 1, p. 363.) 
EFFECT OF SOIL ON THE COLOURS OF FLOWERS. 
In a late tour through the midland parts of England, I observed that the 
light-coloured wild Poppies grow in a strong soil, the dark ones in a 
gravelly soil, the variegated ones in a loamy soil. I remarked, also, a 
similar difference of colour in the herb Robert, Ragged Robin, and other 
pink and reddish flowers. Now, what I want to know is the cause of 
this, and also whether the same variation of colours might not be produced 
by growing the plants in different kinds of soil in a garden ?
