Forestry Exhibition at Bristol , 1913. 287 
There was rather a large competition in the classes devoted 
to gates and wickets, which formed quite an interesting exhibit. 
The all-important question of Fencing was embraced in 
Classes 9 and 10, the former being devoted to fencing from 
home-grown timber, wherein a very large latitude of design 
was encouraged, and the latter to fencing, more especially 
creosoted fencing, from foreign timber. In Class 9, Sir George 
Cooper, Bart., was awarded silver medal, and in Class 10 
Messrs. Armstrong, Addison & Co., Sunderland, silver medal, 
and Messrs. English Bros., Ltd., Wisbech, bronze medal. 
Class 11 is a very important section, inasmuch as it tries to 
demonstrate sylvicultural principles together with economic 
problems, by exhibiting “ specimens showing quality of any 
timber grown on different soils and situations, and the respec- 
tive ages at which it reaches marketable size and maturity, 
accompanied by a short descriptive statement.” In this section 
Earl Beauchamp was awarded silver medal. 
This exhibit would be rendered more educational if, say, 
fuller detailed statements were given as regards the full crop 
of which the individual trees exhibited are examples, inasmuch 
as the exhibit would then be a guide to a correct period of 
rotation, or otherwise demonstrate that the period of profitable 
rotation must be treated on the merits of the particular case 
accruing from such factors as soil, situation, &c. In view of 
the fact that we have few working plans on estates, information 
of this kind would be valuable, more especially to owners 
within the show area. 
Class 12 solicited “ Specimens of Stems , and Boards cut 
from them not exceeding 6 ft. in length, illustrating the effects 
of dense and thin crops in branch suppression and quality of 
timber.” Earl Beauchamp was awarded silver medal. 
This is a very important exhibit, inasmuch as it demonstrates 
the value of density in the younger stages of the crop. But 
something should be further devised to demonstrate the value 
of density according to species, having regard to the initial cost 
of planting, For example, in the case of a pure crop of Scots 
Pine planted at 3 ft. apart a great number soon fall behind in 
the struggle for existence, and so at twenty years of age, follow- 
ing good management, we get a very good numerical strength 
asserting themselves as the “ survival of the fittest.” The 
nature of a pure crop of Scots Pine is that the individual trees 
do not grow equally in height in the younger stages, and so the 
subsequent strong ones are improved in type — in fact a correct 
type — as the result of the struggle. On the other hand a pure 
crop of Spruce planted at 3 ft. apart (being generally considered 
too close for this species) would at twenty years of age present 
a crop of weakling poles, all equally weak, as the result of too
