Fifth Meeting. 7th June, 1871.
F. W. Irvine, M.D., in the chair.
1. The Chairman read a letter from His Honour the Superintendent, with an inclosure from Dr. Hector, respecting a proposed expedition to Cape York for the purpose of witnessing the total eclipse of the sun on 15th December.
2. “On the Varieties of Food for, and Management of the Silkworm,” (Part II.), by T. C. Batchelor.
The author gives extracts from various recent publications on the subject, to compare with the results of his own experiments, which show:—
(1.) That the leaves of Morus alba are inferior in size and quality to those of M. multicaulis.
(2.) That the leaves of the latter when grown on hill-sides are thicker and, though smaller, more valuable than those from trees grown on level ground.
(3.) That Morus alba grows as freely from cuttings as M. multicaulis.
(4.) That the seeds from four successions will produce cocoons of equal quality with the original, therefore disproving any necessity of degeneration—an hypothesis that has been put forth to account for the low price of the silk grown in Australia.
(5.) That he has raised successfully the Lombardy Buff and Japanese cocoons, both of which are highly esteemed.
(6.) That he can successfully delay the hatching so as to produce two broods in the year, the latest commencing in November.
(7.) That the silk he has produced can be wound, and equals in quality that produced elsewhere.
He is of opinion that the Morus japonica should be introduced.
In answer to questions, the author explained more fully some portions of his system, and offered to present members of the Association with Silkworm eggs.
