Megass pulp when used by itself invariably yields a stiff hard 
paper, no matter how it ma} r be manipulated in the beater, and more- 
over it is no easy matter to obtain the papers free from coarse fibres. 
Its great strength, as amply illustrated in the case of the specimen 
marked No. i, depends upon a system of gradual beating of the half- 
stuff, whilst, on the other hand, it is readily liable to become overdone 
and consequently work too “ free ” on the machine, the resultant 
paper showing considerable loss in strength. Nos. 2 and 3 show the 
effects of short sharp beating and fast running. When used in com- 
bination with other kinds of furnish megass gives some very useful 
products, the general nature and appearance of the papers being 
considerably altered. The specimens obtained by admixture with 
chemical wood and lallang pulp are especially promising, and further 
the harsh, effects of the megass are neutralised and a softer feel and 
altogether superior surface is imparted to the finished paper. 
It is a matter of regret that more experimental investigation 
could not be provided in connection with the “ bamboo-megass ” 
combination; however, the excellent effects obtained by running the 
megass pulp in conjunction with lallang fibre :seem to justify the 
statements made by Mr. de Lamarre with regard to its future 
development and enhance the prospects of ultimately making paper
