152 THE ORCHID REVIEW. 
loam, one of peat, and another of chopped moss, and mixing in a few 
nodules of lime-stone or “tufa” during the process of potting. A warm 
and light position in the Intermediate house is the one most suited to its 
requirements. The members of this section should not be watered in the 
ordinary way, but immersed to the rim of the receptacle in a pail of water, 
thus lessening the chance of wetting the growths. Black thrips soon do 
harm to the leaves and flower-buds if left undisturbed, and to keep them 
clean and free from insects fumigation should take place monthly, and the 
leaves be carefully rubbed over afterwards with a moist sponge. 
(These plants do not grow in peat and moss in a wild state, but in loam, 
on limestone rocks, and those who have adopted a method of treatment in 
accordance with this fact have found a great improvement in the health of 
their plants. See a note at page 45 of our last volume.—Eb. | 
THE INTERNATIONAL HORTICULTURAL EXHIBITION 
AT HAMBURG. 
FAvoureED by fine weather and a brilliant assembly of horticulturists from 
all parts of the world, the opening of the International Horticultural 
Exhibition proved a great success. 
The Horticultural Society of Hamburg, Altona, and district may be 
congratulated for the admirable manner in which they have carried out this 
great undertaking. The committee of management has been strengthened 
by a powerful combination of the leading citizens; indeed, no effort has 
been spared to make the exhibition one of the chief attractions of the 
German Empire during the next six months. 
The happy selection of the beautiful park between the Holstenthor and 
Millernthor augurs well for the promoters. Easily accessible from all parts 
of Hamburg, it will no doubt form a favourite pleasure resort. During the 
past six months architects, landscape gardeners, and several hundred of 
labourers have been busy laying out the grounds and erecting suitable 
buildings, and the transformation is an agreeable surprise. 
Everything appertaining to horticulture is represented, and it would fill 
the pages of the O.R. to give an adequate description to guide those 
seeking information ; an official programme, admirably compiled, is on sale 
everywhere in the grounds. 
The prize list for Orchids, though a very tempting one, brought out a 
moderate competition only. Baron Sir H. von Schréder, The Dell, Egham 
(gr. Mr. Ballantine), staged an exceedingly rich and valuable group of 
Orchids, which formed one of the chief attractions to the many visitors of 
the show. One remarkable feature was a fine series of choice forms of
