that the manure acted by precipitating and 
putting out of action certain injurious 
^ub^uulces excreted by the roots. Atten- 
iar tioii was paid to the effects of both poor 
and good supplies of air to the roots, and 
to the necessity for a good supply. In 
j conclusion. Mr. Hall stated that the theory 
of the indifference of the plant to 
the amount of nutrients in the soil was 
found to be untenable. 
A German NationaB Park,— Ten 
I years since Professor Lauterborn, reoognis- 
^ i ing the fact that agricultural and iiidus- 
I trial progress in the German Empire had 
V I brought about the destruction of certain 
members of tlie flora and fauna, proposed 
that a “ Naturschut^parkshould be es¬ 
tablished for native plants and animals. 
, Subse<juent to this proposal ibeing made, 
Only acknowledged botanists will be allowed 
to gather the wild flowers, and even such 
permits will be granted only under the 
most stringent conditions, since, as is 
stated in the official minute, it .is owing 
to their scientific zeal that certain species 
have been practically annihilated in the 
Haardt and in the Ehine Valley. 
Transmission of Plants 
throug:h Italy.— In consequence of the 
strong representations made by the Board 
of Agriculture, the Italian authorities 
have given permission for the transmission 
through Italy of parcels containing plants, 
se^s, and bulbs, provided they are trans¬ 
mitted in sealed receptacles. This condi¬ 
tion is fulfilled in the case of parcels for 
India and the Far East generally, sent in 
transit through Italy; and there is accord- 
BRASSO-CATTLEYA VEITCH 
THE DELL VARIETY. 
Many and beautiful as are the brasso- 
oattleyas now it is very doubtful whether 
any exceed in beauty those produced by 
crossing Brassavola Digbyana with Cattleya 
Mossije. This combination was the first 
of the series of hybrids derived from B. 
Digbyana, and first flowered in 1889, at 
Chelsea, where it was raised for Messrs. 
James Veitch and Sons by Mr. J. Seden. The 
Chelsea nursery could hardly contain Mr. 
Seden on the day that this new hybrid 
opened its large, bright bloom, and showed, 
by the wonderful fringing of the large label- 
lum, the possibilities that lay in the use of B. 
Digbyana as a parent. Many lovely forni» 
of this original brasso-oattleya have

at least a week by sending parcels “via

form of C. Mossise as parent are among 
the most exquisite orchids we have. Queen 
Alexandra and Princess Victoria are varie¬ 
tal forms, and there is a particularly pleas- 
ing hybrid with large white flowers. It 
was deriv€>d from B. Digbyana and C. 
Mossise Wagneri. Another grand white 
form, with a pale yellow area at the base 
of the wonderfully fringed lip, is The Dell 
variety, here figured. This was exhibited 
at Westminster on October 22 last by Mr. 
Shill, gardener to Baron Bruno Schroder, 
The Dell, Egham, when it obtained a First 
Class Certificate. An especially handsome 
coloured form of B.-c. Veitchi—^the Weston- 
birt variety—belongs to Lieut.-Colonel Sir 
George Holford; it gained the coveted 
F.C.C. in 1904.
