Malic grows his Strawberry plants without shelter, 
and for this reason many of his fruits were far from 
having attained the desirable maturity. A certain 
number, however, were remarkable. Marechal 
MacMahon is a fine variety as to taste, perfume, and 
coloiu’; Merveille (not to bo confounded with Ananas 
Morveille), is a superb and oxcellout fruit; Plidno- 
mene is better than fine ; TModorc Mulie is very 
productive and very hardy; Hdldne Mulie is dis¬ 
tinguished afar off by its lino deep colour, an early 
variety of first quality. M. Mulie also exhibited 
.several new seedlings -whose good qualities were 
liighly spoken of, but their insufficient maturity did 
not permit the jury to appreciate them. One 
of the novelties -n'bich was presented under the No. 
], was to bear the name Rameau; it is the issue of 
Marguerite (Le Breton), fertilised by Marechal Mac- 
Mahon, and has both good ilavour and good looks, 
without being very rod in colour. Tho variety 
named Secretaire Rodigas, if it unites tho qualities 
of its ascendants, says the reporter, -vvill have a great 
future before it. HI. Van Warn boko exhibited sonio 
remarkable dishes—superb Mine. Ball, a ^'ery early 
and very deeply-coloured v.ariotj'; Due de Malakoff, 
romarkablo; Thdodore Mulie, finer and riper than 
those from M. Mulie himself; some splendid beri’ies 
of Louis Vihnorin and Professor Pijnaert, 2.^ in. in 
diameter and Sin. in circumference. The banquet 
W’hich followed tho exhibition was successful in all

POTATO MEMORANDA. 
)E hope to learn from extensive potato- 
growers this season what kinds have 
stood the disease best. Here, after 
lifting a number of kinds, we fiild the Early 
Kidneys of sorts, American Eose, Grampian 
(a red-skinned variety of the Fortyfold type). 
Snowflake and Fortyfold as free as any; but 
all are touched more or less, though nothing 
like so bad as many I have seen in various 
parts of the country. On our heavy clay land 
I adopted a method of planting, which, though 
not new, has been very successful,—the crops 
being heavy, and the Potatos large and of 
excellent quality. The ground was ridged up 
roughly and exposed to frost. In April the 
bottom of the trenches were forked over, the 
Potatos planted, then covered with some fine 
siftings of ashes and trimmings of turf-edgings. 
The ridges were forked down over the tubers 
and rounded so as to form low ridges, no further 
earthing-up being done. While many around 
us were despairing of securing a Potato crop, 
the tops dying-off in many cases, and others 
not coming through the ground at all, ours, in 
these nests of ashes and turf, were all one could 
desire ; the crop turned out of them clean, 
and the ground is much improved by the 
porosity caused by the rough turf. The whole, 
after digging the Potatos, was trodden down 
and levelled for turnips, &c.—M. T. 
PLANT DISEASES. 
^cEAE. COENU has recently published, in 
^ q y the Comptes Itendus of the French 
Academy, the results of his observa¬ 
tions on the Plant Diseases caused by the 
attacks of certain microscoj)ic fungi, to wit, tho 
Feronospoi'ce, one species of which, the Ferono- 
spora infestans, has been pretty clearly proved 
to be the cause of the potato disease. One of 
these diseases—that of the Lettuce—and the 
remedy, have been briefly noticed at p. 48. 
M. Cornu reserves more complete explanations 
for publication hereafter, but has already in 
the work above referred to given a useful sum¬ 
mary of the mode in which the parasites may 
be battled wdth. 
First, in order to prevent the extension or 
local production of the parasite, the period of 
its existence should be noticed. In the case of 
those which occur early in the season, endeav¬ 
our should be made to retard the crops until 
their disappearance ; while with those which 
occur later on— F. infestans, for example—tho 
crops (as of potatos) should be got up before 
their appearance. Infested lejives should bo 
removed, so that the plant may not contami¬ 
nate others ; but should the entire plant be 
attacked by the disease, it should be got rid of 
at once, since it is a hot-bed of infection. This 
should be done with precaution, in dry weather, 
when there is neither wind nor dew. All seeds 
which may harbour the parasite should, -with¬ 
out exception, be destroyed. In the case of 
F. ffangliiformis, all Composite plants, such as 
Cirsium arvense, should be removed, and it is 
necessary to watch attentively such subjects as 
Chicory, Artichokes, &c., which may be con¬ 
sidered as pest plants, and their cultivation, if 
necessary, must be given up. 
All plants, or portions of plants, whether 
green or rvithered, infested by the Perono- 
spora or its mycelium should be removed and 
destroyed. They should be plunged at once 
into a solution which destroys the parasite— 
chlorate of lime, sulphate of potassium, &c. 
The green portions left on the ground may, in 
damp weather, produce fresh spores, while the 
withered portions may contain resting-spores.
