NEW BEUNSWICK FORESTRY CONVENTION 



distance of about one inch, stripping the fibres clean for a width of about 

 one-eighth of an inch, thus leaving a well-defined mark which may be 

 traced on the surface of the post for several weeks. 



EXTERIOR VIEW OF NEST 



Flying to the nest with the material thus gathered, the insect then pro- 

 ceeds to incorporate it in the general fabric in such a way as to produce a 

 strong felt which is capable of withstanding the stress of storm, and of 

 affording an ample protection to the brood within. The general result is

ihe construction of the nest upwards of a foot or more in diameter, with the 

 apex pointing downward, the walls of which are multi - seriate, and thereby 

 present a succession of air cushions which secure the necessary protection 

 against changes of temperature. 



WASP PAPER. NATURAL 



Under the microscope the paper is seen to be made up of loosely-felted 

 fibres, which, in the majority of cases, are completely separated from one 

 another, though, in a few cases, they may be found united in small groups. 

 In all about six such fibres make up the total thickness of the paper, which 

 varies somewhat, but on the average amounts to the 1-25 of a millimetre. 



WASP'S PA-PER. SEPARATED FIBRES 



If a portion of such paper is now macerated and teased out in water, 

 the individual fibres may be readily separated. It will then become apparent 

 that, in the majority of cases, they represent the completely-separated fibres 

 of the original wood, while here and there may be seen a few cells still 

 united. Such an analysis also discloses the interesting fact that while the 

 color of the paper is fundamently due to weathering of the fibre, it is also 

 due, in large part, to the presence of numerous filaments and spores of dark 

 brown fungi, which give rise to blackish spots and streaks. 



Here then, we find a paper constructed upon the identical principles 

 which underlie our modern processes, but produced by the most primitive of 

 aft paper makers whose origin antedates that of even the ancient Egyptians, 

 .and it thus becomes evideat *hat the use of wood pulp in the manufacture of
