in a pair of pliers to touch with its pollen the pistil of the bloom to be 
impregnated. In this case, again, the blooms were not protected in any 
way. 
LILIuMs. 
LL. speciosum roseum Xx L. auratum gave progeny but little differing 
from the seed parent; this progeny crossed again with LD. auratwm gave 
a great variety running from pure white through L. s. rosewm up to 
L.s. rubrum ; many of the white seedlings were highly papillose upon the 
inner surfaces of the divisions of the perianth and then to the extremities 
of those divisions ; and while there was not one L. awratwm among all 
the seedlings, all of them showed the parentage strongly in the foliage. 
Unfortunately I imported about this time some lily bulbs which 
must have had disease, and so saturated my garden with lily disease that 
I practically lost every lily had. Method of crossing is the same as with 
Hippeastrum. 
SPORTING. 
This is a subject allied to hybridisation, probably the cropping out of a 
latent effect of the hybridisation of an ancestor, and it seems that with 
. either old age or ill-treatment there is a probability of such a sport. Thus 
from an old plant of ‘La France’ rose I have had sports, both ‘Mlle. A. 
Guinoiseau’ and ‘ Duchess of Albany’; from ‘ Princess Alice’ carnation 
under similar circumstances have sported both white and pink selfs, and 
these sports have been readily fixed by taking off cuttings high up on 
growths showing the sport ; so also with chrysanthemums. 
GRAFT HYBRIDISATION, 
I have only commenced this, so cannot say I have achieved any results ; 
but I will mention two things that happened in my garden. A twenty-five- 
year-old rose ‘Ethel Britten’ budded on American noisette developed 
from the neighbourhood of insertion of the scion a shoot that had a 
bloom which puzzled some of our best rosarians, who, not knowing what 
it was, pronounced it midway between the two (stock and scion) ; and an old 
neglected plant of rose ‘Souvenir de M. Métral’ budded on American 
noisette developed three shoots from about the insertion of the scion. 
These grew as American noisette stems, thorns, and foliage for a foot or 
eighteen inches, and then in response to a little kindly treatment all the 
shoots continued as ‘Souvenir de M. Métral,’ and eventually bloomed true 
to that variety. 
BIGENERS. 
I cannot say I have had much success with hybridising between two 
genera—certainly I raised two bulbs by crossing a Crinwm with pollen of 
a daffodil. At first the foliage gave great promise, being bifarious, but 
gradually in one it changed and became turbinate as in the seed-parent 
—the other is about midway in habit of foliage; but the bloom of both © 
is merely Crimwm, and both are thus far sterile though they have bloomed 
for several years, and have been worked with pollen of both parents. The 
Crinum parent is a most prolific seed-bearer. Another attempt was
