GUMS, RESINS, AND KINOS. 217 
The gum from this tree forms good adhesive mucilage. It 
reminds one strongly of East-India gum arabic of good quality. 
During the summer months large masses, of a clear amber-colour, 
exude from the stem and branches. It has a very pleasant taste, 
is eaten by the aboriginals, and forms a very common bushman’s 
remedy in diarrhoea, &c. A sample in the Technological Museum 
is half as large as an emu-egg, and is frequently obtained in 
pieces as large as pigeons’ eggs. It would be readily sought 
after in the colony for adhesive purposes if it could be obtained in 
any quantity.

A clear, hard, yellowish gum (? gum resin) has been observed 
on this'shrub in the Illawarra district of New South Wales. In 
the catalogue of Western Australian products at the Intercolonial 
Exhibition, Melbourne, 1866, it is stated: ‘‘ Gums of Wakea species 
are found plentifully after the autumn rains.”

Mr. C. R. Blackett, of Melbourne, describes in the Australian 
supplement to the Chemist and Druggist, May, 1882, some 
experiments upon the gums exuded by the above two species. A 
quantitative examination remains to be made, but Mr. Blackett 
states that the gums are analogous to Bassora gum, or tragacanth, 
but whether they can be used instead of tragacanth remains to be
