quickly reaching the bottom of the pan, and then spreading laterally. I think 
it right to add, that the colour of the flowers was not at all the worse from this 
method of propagation, which I have now tried for the last two or three years 
with equal success. 
As to the notice stating the beauty and length of the spikes, in flower at the 
same time, of Erysimum Pereskiianum, see Harr. Flor. Cabinet for December, 
1839, and the plate in the same number,—although you have shown Mr. H. 
very clearly to be no authority. 
I shall be obliged by your informing me, in your next “ Letter-box,” the 
best method for encouraging the growth of moss on a grass plot in a low 
situation, where the best hill turf very soon changes into very coarse grass. 
Also, as to the best method of growing, and the colour of Lisianthus Rus- 
sellianus. 
The Crassula cocci nea , the cause of the failure of which you so well explained 
in your first “ Letter-box,” has now recovered, and is showing well for 
blossom, and the side shoots taken off bid fair to be strong plants. 
R. W. B. 
Note by the Editor. — Lisianthus , or rather Eustoma Russellianum, is a 
hardy annual, a native of Texas; and therefore it requires nothing further 
than the ordinary treatment of hardy annuals,—to be put in good mould well 
pulverized. 
R, W. B.’s other question is rather a curious one ; the object of most people 
being to keep moss off grass plots, and not bring it on. To bring moss any¬ 
where, the plan is, to give the place where it is desired a sprinkling of the soil 
immediately under the growing moss of the kind wanted, and then to keep the 
surface moist and occasionally under a small depth of stagnant water. The 
w'ater must not be allowed to flow over it, otherwise it would wash away the 
sporidae of the moss ; and it must not be allowed to stand too long at a time. 
We suspect, however, that if the plot is so low and humid, as to change hill 
grasses into coarse meadow ones, the bringing of moss upon the surface would 
be the first step towards a bog. Therefore, a better plan would be to secure an 
under-drainage, by a porous stratum under the turf, to prevent the water from 
stagnating on the surface, and so to preserve the hill grasses, if possible. If 
the creeping white clover is not objected to, sowing the surface with river sand 
and a little peat earth will secure that, sometimes without the expense of any 
seed. 
FLOWER SHOWS. 
Horticultural Society of London. 
On Saturday, May the 15th, 1841, the first Show of the season was held at 
the Horticultural Gardens, Turnham Green. The day being propitious, a large 
assemblage of the nobility and gentry attended. It was pleasing to observe 
the great delight taken by them in admiring either the horticultural productions 
exhibited in the tents, or the beauties of nature when promenading the gar¬ 
dens. As it is the public rendezvous for all the great fashionables, the array
