OcrToseER, 1910.] THE ORCHID REVIEW. 301 
Lindley’s original type of the species. Another had a well-spotted flower 
recalling a form of O. X Ruckerianum in this respect. With them were 
several diverse forms of O. x Adrianz, one of them belonging to the yellow 
spotted type, O. Lindleyanum, two good O. x Wilckeanum, O. constrictum, 
and O. X armainvillierense xanthotes with four side branches to the 
inflorescense and an aggregate of twenty-five flowers. A seedling from O. 
X Ruckerianum crossed with O. Hunnewellianum had flowers with a yellow 
ground, recalling O. X Adrianz in most respects. Cochlioda Noetzliana 
x O. polyxanthum had a yellow flower with only a tinge of red. A small 
seedling from O. crispum Speculation crossed with O. c. Pittianum was 
nicely blotched and very promising. 
The establishment at Cooksbridge has a reputation for Odontoglossum 
culture, and Messrs. McBean attribute their success largely to the amount 
of light which the plants receive during the winter months, when growth is 
taking place. The extension of the hybridising department, which is now 
in progress, should therefore yield some interesting results in the near future. 
CALENDAR OF OPERATIONS FOR OCTOBER. 
By W. C. Price, OAKDENE, WEsT DipsBury. 
Durinc the dull months, when there is not much potting to be done, 
everything should be thoroughly cleaned, so that a good start can be made 
next season. Potting materials may also be prepared ready for a start next 
year, and so save valuable time which can ill be spared when the potting 
season proper arrives. Loam, peat, polypodium and Osmunda fibres can 
all be got ready, and stored away in a suitable place, leaving out the 
sphagnum moss, which must be added at the time of using. Crocks for 
‘crocking the pots may also be got ready. 
Owing to the sunless season we have been having lately, great care 
should be taken to harden up the plants as much as possible, and due 
attention paid to the watering, damping and ventilation. The blinds will 
not be needed now, except perhaps on the Odontoglossum house, and a few 
of the softer-leafed section, and then only during very bright sunshine (if we 
get any more). 
TEMPERATURES for the different departments for the coming month 
should be as follows :— . 
Cypripedium house, day, 68° to 72°; night, 68°; morning, 63°. 
Cattleya house, day, 65° to 68°; night, 65°; morning, 60°. 
Intermediate house, day, 62° to 65°; night, 62°; morning, 58°. 
Odontoglossum house, day, 58° to 60°; night, 58°; morning, 55°. 
ANGuULOAS, in the Intermediate house, have now finished up their bulbs, 
and should have the supply of water gradually reduced, and only sufficient
