42 CHRISTISON—ADDITIONAL OBSERVATIONS ON 
In No. 3 the average annual rates in the two quinquennia 
were about 3 and 12 mil., and the increases of 19 and 18 in the 
years 1905 and 1906 augur well for the future of a tree of the 
species already 4 feet in girth, 34 feet high, with a bole of 9 feet. 
4. CRATAEGUS OXYACANTHA, var. FLORE PLENO. 
This considerably smaller hawthorn followed much the same 
course as No. 3, but the quinquennial averages of about 2 and 
11 mil, were rather less than in it, and the increases of 10 and 19 
in 1905 and 1906 compare unfavourably, considering the smaller 
girth, barely 2 feet, of No. 4. 
5. JUGLANS REGIA. 
This remarkably handsome walnut is the largest “transplant” 
in the Garden. When operated on it measured within 3 inches 
of 5 feet in girth, and had a stem of 17 feet and a total height 
of 50 feet. With its ball of earth it must have weighed 
about 7 tons. 
After transplantation its progress, if progress it can be called, 
was exceedingly slow, and it was no better in the second 
than in the first quinquennium, the amounts being 64 
and 6°3 mil., or 12°7 in ten years. 
The annual increase was zz/ in 1896, ’99, 1901, 05; and the 
greatest amount in any one year was 3°8 in 1900. This is a 
disheartening record ; nevertheless, the tree retains its fine appear- 
ance, and, if the foliage continues to be very poor, it is not 
unhealthy and there are few dead twigs. It is to be hoped, 
therefore, that recovery will eventually be complete, and that an 
interesting proof may be furnished that a tree, after “marking 
time” for at least ten years, may enter on a fresh career of 
progress. 
The results in Crategus Oxyacantha, No. 16, another large 
hawthorn, may appropriately be given here. The effects of trans- 
plantation in this tree were complicated by the effects of frost. So 
far back as 1878 this was by far the finest hawthorn in the Garden, 
symmetrically clothed with dense foliage to the ground. It 
girthed 3 feet 2 inches and the increase of that year was 204 mil., 
but the disastrous frost of that winter brought it down to 2} in 
1879: in 1880 it rallied to 19, but the hard frost of that winter
