fereiice to the conditions which probably 
(itained during the gro^h of these lime¬ 
stone-forming plants, it is suggested that 
the oolitic deposits and dolomites, with 
which they are closely associated, accumu¬ 
lated in wide lagoons, similar to those which 
now exist in the neighhourhood of coral 
reefs, and in sheltered, submerged plateaux 
a> may be found at the present time in the 
Bay of Naples. The general conclusions 
of Professor Garwood are that during the 
periods at which these growths took place 
there v/as considerable elevation or sub¬ 
sidence of the land areas. 
Export of Potatoes to 
America. —The Horticultural Board at 
Washington has decided to continue in¬ 
definitely the quarantine against potatoes 
from Great Britain, Germany, Austria, 
Newfoundland, St. Pierre, and Miquelon, 
notwitlistanding the request of tlie British 
Board of Agriculture that the quarantine 
on Great Britain should be raised or 
modified. 
Lawes and Gilbert Centenary 
Fund. —Next year (1914) is the centenary 
of the birth of the late Sir John Lawes, 
and 1917 is that of the birth of Sir Henry 
Gilbert, and it is proposed to celebrate the 
occasion by erecting a suitable Commemora¬ 
tion Laboratory at the Rothamsted Experi¬ 
mental Station, which these distinguished 
agriculturists founded. For this purpose 
the sum of £6,000 is required to be raised 
by public subscription. Everyone interested 
in agriculture and horticulture owes a debt 
to the work of Lawses and Gilbert at Roth¬ 
amsted. It was they who first demon¬ 
strated in this country the value of arti¬ 
ficial manures, and their experiments, more 
than any others, showed what these could 
do, and how they should be used. The 
Rothamsted Field Experiments have become 
the model on which practically all others 
are based. They carried out experiments 
on almost all branches of agriculture, and 
obtained results of the greatest value to 
cultivators. The Rothamsted Laboratories 
are further famous as the place wdiere two 
^her distinguished scientists have worked. 
Here it was that Professor Warington did 
^ much for Agricultural Chemistry and 
•u carried out researches that 
hmg continue to bear fruit both at 
^ome and abroad. The changes that are 
giadually taking place in cultural methods 
make It more urgent than ever that the

OCTOBER IN THE ROSE 
GARDEN. 
Judging from the general api>earance of 
rosets at the autumn show^ of the National 
Rose Society, I fear many of my friends 
are not so well off for rose blooms as we 
are in East Sussex. We have never had 
a more pleasing outlook for October, and, 
with the greater profusion of gootl 
autumnal bloomers now* available, our be<U 
are really gay. To name the varietk^s 
would occupy much spa-ce, for most of the 
free-blooming hybrid teas and teas, to¬ 
gether with the dw’arf polyanthas, are one 
mass of blossom, and with quite clean 
foliage. 
In a summer note I mentioned a number 
of iHMpetual-fiowering climbers and pillar 
roses. I w’ould like to add that Climbing 
LilK>rty, Climbing Orleans Ros<' ajid Climb¬ 
ing Richmond are great acquisitions, and 
there i.s no necnl to grow* such a lot of our 
extra vigorous varieties, which only carry 
one good ci*op of blossom each season. I 
think it was in the issue for July 12 that 
the few notes referrinl to appeartnl, and I 
would like to remind intending purchasers 
of the varieties then menthkiUHl. 
One cannot have a lietter tim<‘ than the

MTiere plants have been, or are still, suf¬ 
fering from mildew, red rust, and black 
spot which I fear have been rather pre¬ 
valent this year (if one is to judge by the 
numbers of queries I have received re¬ 
lating to these diseases), it will be wise 
to collect and promptly burn all fallen 
leaves as soon as possible. There can be 
no doubt that these fallen and affected leaves 
wdll spread disea.ses next season as soon 
as weather conditions and young growth 
favour their development once more. There 
can be no material benefit from rose foliage 
as a future plant food, so it is better to 
collect and burn it. 
settle down a little and, unless ready, one’s 
rose plants are not always put in so 
promptly as many desire. 
Examine and be prepared to house pot 
roses at any time now, for bad weather so 
often comes unexpectedly, and causes a 
confusing rush of work if one is not duly 
prepared. Our maiden standards are in fiiil 
growth and flower. Mdme. Abel Chatenay,
