ACCLIMATATION. 31 
variety, but in plants of the red, or mixed variety, from dif- 
ferent parts of the Continent. The demand, however, for Tyrolese 
and Continental larch plants, and the frequent failure of the 
larch seed-crop in Scotland, has often given rise to large import- 
ations, especially during the cold wet seasons succeeding 1859. 
In this part of the country—Morayshire—we have had the 
most ripening autumn (I now write, 15th November 1865), 
and the driest ever experienced. In these circumstances it is 
interesting to compare the appearance of seedling larch from 
imported seed, with those produced from home-grown seed. 
Of my one-year-olds all are from home seed ; but of two-years- 
old seedlings I have a few thousands from imported seed, 
standing in the same lot with plants raised from home-grown 
larch seed. Both were sown in the same hour; the soil and 
the treatment were in every respect similar. Both sorts have 
now for a season ceased to grow, and are of the full size 
for their age, and are very equal, but the colour of the foliage 
is at present very dissimilar. Those from Continental seed 
appear quite green and succulent, having the terminal bud hid 
among the leaves on the top of the shoot, while the foliage of 
“those grown from Scotch seed has a rich yellow and ripened. 
appearance up to the top, disclosing the terminal bud full and 
plump, and prepared to withstand any degree of frost that 
may occur throughout the winter, or that might have occurred 
for weeks past. The difference between the two sorts is very 
marked, and from the colour of the foliage can be at once 
distinguished as far off as the plants are visible. This circum- 
stance is by no means new to me. I have always found it so, 
but in a season so dry and ripening I would have expected 
that the contrast between the two sorts would have been greatly 
diminished. 
I have occasionally, after severe frost in October and Novem- 
ber, seen plants grown from imported seed that had been trans- 
planted in lines for two years, standing with their tops droop- 
ing, with unripened foliage adhering to the plants for many 
months, while plants from Scotch seed in the same lot, and of 
the same age and treatment, stood scathless,
