there are generally suitable situations to be found for them ; when such 
is the case, the introduction of such plants as Osmunda regalis, Asple- 
nium Filix-foemina, many of the Aspidiums, and, in fact, most of the 
larger-growing British and hardy exotic species, may be introduced 
with the best effect. With regard to such plants as the Typhas, 
Phragmites communis, and many other plants which naturally grow in 
marshy ground, they may be introduced with good effect when the 
water is sufficiently deep, except near the sides of the lakes, to prevent 
them spreading and becoming troublesome. Such plants as the flowering 
Rush (Butomus umbellatus), Menyanthes trifoliatus, some of the 
Alismas, Acorus Calamus, Sagittarius, and several of this class of sweet- 
scented and beautiful plants, should be placed at points on the margin 
of the lake where they could be more closely approached. In Devon¬ 
shire, we have heard of such plants as the Calla sethiopica and some of 
the Hedychiums withstanding our winters, and growing luxuriantly 
during the summer months. With such materials our lakes would 
indeed assume a new feature. These plants, like some of the more 
tender aquatics, escape and grow more luxuriantly when their roots are 
some eighteen inches or two feet beneath the surface of the water. With 
regard to aquatics proper, the Nymphaea alba and Aponogeton dis- 
tachyon are always much admired ; the former spreading its foliage in 
such masses as to become a conspicuous object at a great distance— 
while the latter, being smaller, is more adapted to small lakes and the 
margins of those of large extent. The Potamogetons, though interesting, 
and many of them pretty, are generally too weedy in their growth to be 
admitted by design into artificial water. 
Though the names of such plants as would serve to contribute variety 
and beauty to our lakes might be much further extended, the present 
will suffice to show that there exists an abundance of material, and it 
only requires the good tact of our amateur and professional gardeners to 
give a charm to such features as they have hitherto but too rarely 
possessed. 
' ROSES. 
Richlieu, of Brussels, describes a first class Rose thus, and says it 
applies to all Roses;—First, the petals should be thick, broad, and 
smooth at the edges. Secondly, the flower should be highly perfumed. 
Thirdly, the flower should be high on the crown, round on the outline, 
double to the centre, and regular in the disposition of the petals. 
This is certainly a first-class description of a Rose, but I fear there 
are few first-class PerpetuaJs, as they generally lack the second attribute. 
Of those which I have or which I know, the three that come nearest to 
the first and third rule are William Griffith, Prince Leon, and Madame 
Laffay, an old but first-class Rose. William Griffith is the most perfect 
in shape and thickness and regularity of petal. Prince Leon is brighter 
in colour, and scarcely inferior in shape, disposition and thickness of petal. 
Madame Laffay is perfect in shape and colour, but not quite so thick in 
petal, though equally well disposed.
