The Bouche d'Erquy in 1906. 
1904 bore a fairly pure apple-green type of Salicornia. To a slight 
extent last year, and this year in marked degree, the crimson form 
ousted the green. So much so that in extreme cases areas 
previously green had become wholly red. 
The work of Section D (“Transplantations and Heredity 
Problems ”) dealt largely with the sort of problem exemplified in 
in the last paragraph. 
In 1905 about a dozen reciprocal transplantations were made, 
whilst at Easter this year a very large number of small sods of 
seedlings were interchanged between the principal habitats. The 
scrutiny of these and the carrying out of such additional trans¬ 
plantations as gave promise of yielding useful data fell to the lot of 
this Section. 
The object of a transplantation is two-fold. First, there is the 
direct action of the new habitat upon the plants when they have 
settled down in their new surroundings; secondly, and perhaps 
more important, in the event of seed being ripened or dropped, 
there are the characters shewn by the plants of the next generation. 
In this way, in two cases of last year’s transplantations, the apple- 
green form of Salicornia seemed to have perpetuated its type in the 
seedlings arising after it had been transferred to two other quite 
distinct habitats. However, results such as these must be accepted 
with some reserve, for analysis of the portions of soil that accompany 
the transplantations shew them to be somewhat retentive of their 
former properties as regards both the amount and salinity of the 
water held. It is evident that, as a method, transplantation must be 
employed with discrimination and should be checked by actual 
sowing of seeds in appropriate natural or artificial habitats. 
Several series of dibblings of seedlings which were made in April 
with this object in view, were, on the whole, a failure, owing to 
difficulty in effecting establishment. This difficulty may have been 
aggravated in this instance by the abnormal drought; but, be this 
as it may, the problem of stability of characters seems best capable 
of attack by planting the seeds themselves. 
The same section gave some attention to studying the mode of 
pollination of the Salicornias and performed a number of crossings 
—an operation of some difficulty, the success of which remains to 
be proved. 
Section E (“ Denudations and Migrations ”) devoted considerable 
attention to an investigation of the physical effects of baring the 
soil, and to a comparison of the vegetation of bare and covered
