268 THE ORCHID REVIEW. [SEPTEMBER, 1908. 
its character, but swampsthat of the other, giving such a result as might 
have been expected if typical forms of the species had been used. The 
crossing of a pure albino with one in which the purple colour is only 
present in minute quantities should not be the same as when the ordinary 
coloured forms of both species are used, and the phrase about throwing 
C. insigne Sanderz overboard was only used in this connection (see p. 142). 
The problem now seems to be why C. insigne Sanderz when self- 
fertilised does not revert to an ordinary coloured insigne. The colour is 
clearly there, even if only in minute quantities, and it seems to require the 
influence of C. X Maudiz to bring it out, and yet C. X Maudie, as already 
shown, is not a colour bearer. The inference is that the difference lies in 
their action upon each other when combined. The two have a different 
ancestry, and a different course of development, producing when combined 
an inharmonious blending, and a struggle for supremacy, accompanied by a 
certain amount of reversion. This, of course, is equally the case when C. 
insigne Sanderianum is crossed with C. X Maudie. The result in either 
case is a hybrid, a kind of compromise between two divergent courses of 
development, but in the latter case we may perhaps assume that the 
absence of colour from both parents leaves no material to work upon, and. 
any reversion would manifest itself in some other direction. It would now 
be interesting to compare the home-raised C. insigne Sanderze with the 
wild original, to see if any kind of discrepancy can be detected. 
We know the hybrid raised from the albino Cattleya Mossia Wageneri 
X Brassavola Digbyana (O.R. xiv. p. 339), and it is curious if C. M. 
Reineckeana X B. Digbyana gives a similar result. We should like to 
see a flower. It would be interesting to self-fertilise it, to see if reversion 
or dissociation takes place, and the remark applies equally to the cases 
previously mentioned. An interesting problem evidently awaits solution. 
Continued experiment will probably throw more light on the subject and it 
seems particularly desirable to test the constancy of some of the supposed 
reversions. mR, A. K

SHADING should all be removed by the end of September, and the glass 
washed outside and inside to admit all the light possible. Where canvas 
blinds are used they will be better taken off the houses, and well dried and 
stored away for the winter, as frost and rain soon rots them. Where the 
lath blinds (or bamboo blinds) are used they will be found very useful as a 
protection from frost. We run ours out every night trom September till 
April, and find it makes a:considerable difference to the coal bill, and we do
