bottom of a china jar in which the plant was placed; it was then covered 
nearly over with the same materials, and as roots were made they were 
covered with more moss ; it was then suspended over the flue where the fire 
comes into the house, and a large waterpot with a syringe was always 
ready to give the plant a plentiful supply of water at every opportunity, 
by which means that part of the house was always kept moist 
My success has been such with the above treatment as to produce six is 
of flower on a single plant.” The plant in question had been brought 
from China in 1824 by Captain Mitchell. 
In the same volume of the Transactions of the Horticultural Society may 
be found a paper (p. 203) entitled, ‘‘An Account of a Plan of Heating 
Stoves by means of Hot Water, employed in the Garden of Anthony 
Bacon, Esq., F.H.S.,” by Mr. William Whale, gardener to Mr. Bacon, in 
which the writer remarks that after twenty years of experience in forcing, 
both with brick-flues and steam, he certainly gives preference to the 
method which Mr. Bacon has adopted of heating his houses with hot water. 
The system was first put in practice on a small scale by Mr. Bacon at his 
seat at Aberamen, in Glamorganshire, in the year 1822. The new system 
was not invented for the purpose of Orchid growing, but it deserves to be 
mentioned here, for it gradually effected a complete revolution in plant- 
growing under glass, and contributed in no small degree to the improve- 
ment in Orchid culture which subsequently followed.

TREVORIA CHLORIS. 
Tuts very interesting Orchid has now flowered in the collection at Burford, 
under the care of Mr. White. It was described and figured as a new genus 
in May, 1897, by Mr. F. C. Lehmann (Gard. Chron., 1897, Xxi., p- 345: 
Suppl., fig. 128), as follows:—‘‘ My first acquaintance with Trevoria 
Occurred in 1887. Only three specimens were seen, bearing thin, drooping 
spikes, about 4o cm. long, of thickly set seed-vessels, but no flowers. The 
Plants I tried to take to the Cauca for cultivation, but alas! they were 
Stolen from me by some rascal at Esmeraldas during my absence from the 
Steamer, together with a number of other botanical treasures. Nothing 
More was seen or heard of this plant, which by-the-by looked quite novel 
and interesting, until last year, when during an exploration of a certain 
Portion of the Western Andes of Colombia, with a view to projecting a 
map on behalf of the Cauca Government, a few plants of this species of 
Orchid were observed. The species found in Colombia is, however, quite 
distinct from that of Ecuador. The latter grows at an elevation of 500
