crevices amongst the stones, 'where the roots will be kept fairly 
dry in winter. It does not seem to seed very freely, but 
propagation may be> effected by taking off young crowns and 
inserting them firmly in sandy soil in thumb pots. 
Potentilla nepalensis minor. 
The ordinary form of P. nepalensis. is an old-fashioned border 
plant which is frequently more neglected in collections than 
it ought to be. Usually, it grows about 18 in. high, though 
occasionally it may be taller in particularly rich soil. The 
variety under notice is much smaller, both in the leaves and 
the stature. Usually the stems assume a spreading direction, 
as they would when growing upon rocks, so that it should be 
planted near a ledge of the rockery, where the stems could hang 
over without interfering with any other plant. This miniature 
form has stems about 6 in. or 8 in. long, and bright yellow 
flowers, with a scarlet blotch at the base of each petal. 
Campanula tommasiniana. 
Most Bellflowers are' bell-shaped, but- that scarcely applies 
fj the species under notice. The pale blue-purple flowers are 
almost tubular; indeed, might be described a.s^ such, and freely 
produced on the top of the stems, which gradually lengthen 
to 12 in. during the course of the summer. The species is a. 
native, of Istria, and is well worthy of cultivation on the 
rockery, where it forms a dense mass of stems and flowers that 
hang gracefully over the stones or ledges. M. W. 
Notes on a Private Garden. 
I. 
In the capacity of a journeyman in a. private garden in, 
Scotland, I purpose dealing with a few subjects which come 
under our observation, and that same to be chiefly pertaining 
to horticultural interests. I am positive that there is; no other 
gardening periodical which associates itself' with so many Scot¬ 
tish items of our profession as the “ G. W.” Correspondents 
and readers are also very numerous north of the Tweed. 
Encroaching on your space, then, I will, in the first place, 
assign my notes, to. a walk through the pleasure grounds, 
touching briefly on some trees and shrubs. The first to. capti¬ 
vate our attention is the conspicuous bushes of that, variegated 
Dogwood, Corn us Mas variegata, a very handsome type of a, 
shrub, with beautiful white and green deciduous foliage. The 
golden variegated Ligustrum is also very showy. Cerasus 
serrulata, the double-flowering Cherry, is a remarkably rare 
tree to be seen now. In the month of May it had a gorgeous 
appearance, being laden, with its, snow-white flowers. Prunus 
japonica fl. pi. is also, represented. I have not recognised this 
shrub outdoors before. It evidently thrives well. I have (in 
the columns of this paper) advocated its adaptability for forc¬ 
ing purposes. Other forms of the wild Plum exist. Without 
f urther precedence I will mention some of the flowering section. 
Weigela rosea, Philadelphus coronarius, Escallonia 
macrantha, doing its duty to obscure an odd corner. Various 
Honeysuckles, Spiraeas, Viburnum Opulus—the Guelder Rose 
or Snowball tree—are also noteworthy. We could very well 
dispense with the hothouse flowers at, present with such a har¬ 
vest of bloom outdoors. 
A compact, low-growing shrub labelled Castanea chrysophylla, 
would not appear to be in conjunction with the Spanish Chest¬ 
nut (Castanea sativa). The Walnut tree (Juglans regia) fruits 
well in our private gardens in Scotland. Aeseulusi and Fagus, 
sylvatica purpurea are almost invariably in every place. That 
is a very diminutive list I have commented on. The subjects 
for beautifying our grounds is, a, very imperative part at the 
present, day. To acquire a thorough knowledge of these 
shrubs, their means of propagation, soils, and positions, pruning 
(if any) is of the utmost importance. They are by no means 
the rarest shrubs, but are only what is to be seen in one of 
our places in Scotland. Just what we actually observe daily 
gives an idea what it is possible to learn if so inclined. With 
the Editor’s- sanction, I desire to extend my review to the flower 
gardens and other floral borders in a future, issue. [Please do. 
—Ed.]. 
I cannot refrain from including the Tulip tree (Liriodendron 
tulipifera) and Dimorphanthus mandschuricus. The former is 
not so popular as it might be. In sheltered positions it soon 
assumes a very handsome tree. When in flower it, has quite a 
pleasing aroma. The latter is of the Aralia species. In fact, 
it is termed Aralia chinensis, an erect-growing shrub, leaves 
3 ft. long and veiy prickly. I have not seen the flower come 
to any distinction. This Aralia is, in several private gardens 
going under some erroneous names. Some notable specimens 
in the evergreen trees are C'upressus nootkatensis, Araucaria 
imbricata, Wellingtonia, Abies pichta, Thuja semper aurescens. 
Retinospora and its various forms are very much in evidence. 
Cupressus pisifera squarro-sa is the finest evergreen tree one 
could wish to see. Several of them are 10 ft. high. Hollies 
and Yews are in every conceivable shape. Some hedges of the 
latter are 12 ft. wide and 18 ft. high. 
The Largest Map. 
Growing on six acres of a gentle southern slope of Tesson 
Hill at, the Louisiana Purchase Exposition, St. Louis, is to be 
seen the largest, geographically correct map ever constructed. 
The map is 480 ft. long from east to- west, and extends from 
north to south 240 ft. The map is to be the main feature of 
the large open-air exhibit by the Bureau of Plant Industry of 
the Department of Agriculture, and is personally superintended 
by D. A. Brodie. The idea, is to show the United States, with 
growing crops planted as per the natural distribution. 
The several acres were fenced off early in April, and the 
entire tract was richly fertilised. The ground was ploughed 
and harrowed, the soil pulverised, and the entire tract sowed 
to Cow Peas. This crop not only enriches the soil, but pre¬ 
vents the growth of weeds. When an exhibit is ready to be 
installed, the gardeners simply pull up the Cow Peas covering 
the space required, for the ground then requires but little 
work. 
A belt of blue grass- lawn 20 ft. wide establishes the boundary 
and coast lines of this gigantic) map. The boundary lines 
between the States are marked by cinder paths 3 ft. wide. 
That, part comprising the fourteen States and territories of 
the Louisiana Purchase is marked by a white gravel walk. Not 
only will the products of each State be shown on this map 
by growing crops, but the section of the State on which each 
commodity is most grown will be shown.—The Weekly 
Florists’ Review.” 
The Flora of Raratonga. 
" Raratonga is the chief island of the Cook group, situated in 
the Eastern Pacific, between the Tonga and Society Islands. 
Though discovered in 1821,” says “ Knowledge,” “ and occupied 
by Europeans nearly the whole time since, scarcely anything 
has hitherto been published on its flora. Raratonga, is of vol¬ 
canic origin, and is about eight miles long and six broad. Near. 
the sea there is a level tract of land, varying from a quarter 
of a, mile to a, mile in width, extending all round the island, 
while the centre is a mass of rugged mountains, ranging from 
1,575 to 2,250 ft. high. Forests abound, but the herbaceous 
vegetation, except, numerous Ferns, is scanty. With the in¬ 
clusion of nearly 100 species, which have with more or less 
certainty been introduced, the flora as at present known con¬ 
sists of 334 vascular plants, of which no less, than sixty-seven 
are Ferns.. Eighteen specie® belonging to sixteen natural 
orders are probably endemic. Perhaps the most remarkable 
plant amongst these is Fitchia speciosa, a new species, of a 
curious, genus of Compo-sitae, hitherto known only from the: 
Society Islands, where three species are found. F. speciosa. is, 
common on all the mountains of Raratonga. It. is a, small hand¬ 
some tree, with flue glossy leaves and large orange-red flower-, 
heads.”
