March, and the harv'est took place on the 30th June. The ammouiacal water (No. 6) was neutralised by the 
hydrochloric acid of the glue manufactories, and thus a precipitate of phosphate of lime was applied to the meadow.

Potato Disease. — AVe regret to he the fii'st to an- 
nounce the re-appearance of this disease among forced 
potatoes. In the garden of E. Fellows, Esq., Black- 
heath Park, it showed first on Good Friday, the haulms 
having flagged as if struck by lightning ; but, upon ex- 
amination, we found the base of the stem quite covered 
■with gangrene, and the young roots dead. The tubers 
at the j)resent time are not afl^ected, the pit having been 
kept warm and dry ; but no doubt, under ordinary cir- 
cumstances, in the open air, they would have been 
entirely worthless by this time. With forced potatoes 
the best system of management is to shut the frame or 
pit up close directly the disease appears, and keep it as 
dry and hot as possible, until the crop is gathered. — A. 
Frame Frotection. — I am glad you have already 
taken up the subject of coverings for frames, &c. I do 
not think the gardener has a greater enemy than the 
Kussia mat. I do not care, like Mr. Cobden, to pre- 
vent Russia loans, but I own I should like to ruin the 
trade in Russia mats ; they are dear at Is. to Is. %d. 
each. They rarely, even with care, last more than one 
season, and, when wet or frozen, are worse than use- 
less ; and employers ai-e always complaining of the 
annually recurring demand for new mats. We have 
here entirely superseded them by the use of wooden 
shutters the size of the lights, made of half-inch deal, 
supplied fi-om Mr. Montgomery's saw-mill at Brent- 
ford, at 8*. per 100 feet; these are secured together the 
size of the lights, by a lath one inch and a-half thick, 
top and bottom, thus leaving a space for air, between 
the shutter and the glass, and the protection is equal to 
at least thr-eo mats ; and if these shutters ai-e put away 
dry in the summer, they wiU last from seven to ten 
years. We have also applied these wooden shutters to 
the back or north lights of a small span orehid-hotise -sviih 
great success, making, I believe, at least five degrees 
^73 = 
temperatm-e dming the night in favour of the shutters. 
I expect that these will also be foimd very useful in the 
summer for protecting from the sun fresh-planted vege- 
tables, as well as for other shading purposes in the 
garden. The great object, as regards glass, being to get a 
body of non-conducting matter between the covering 
and the glass, I feel certain that we shall never attain 
complete success in orchid culture till we have houses 
with double sashes ; and the cheapness of glass, and the 
facility there is of obtaining large panes, would render 
an experiment of this kind easy and not costly ; indeed, 
double sashes would not be necessary, as the sash-bars 
and frame might be two inches and a-half thick, and 
the rebate at top and bottom, so that it would be a 
double-glazed sash. I suspect, with this protection, 
any degree of moisture and of temperat'oi-e might be 
kept up in the house, with very little fire-beat. — /.

NURSERY CALLS. 
Messrs. Lee, Hammersmith. — March 1. — The collec- 
tions of plants in this ancient nursery are undergoing 
revision and renewal imder the active personal super- 
intendence of Mr. C. Lee, who has already efi^ected 
considerable improvement within a few months. One 
of the most interesting features in the establishment 
is the collection of Cacti, which is very extensive, and 
contains not only an immense number of plants, but 
many very fine specimens in a flourishing condition. 
One or two beautiful species recently figured in the 
Botanical Magazine by Sir W. Hooker, had been received 
at Kew from the Messrs. Lee's collection. One of these, 
Cereus Lceanus, has beautiful vermilion flowers, on 
stoutish upright cylinder-shaped stems ; and another 
more recently bloomed, the Cereus Tweediei, has very 
remarkable and showy bright flame or orange crim- 
son coloured flowers, which are numerous, on the
