eggs by the use of cold-storage, so that they 

 would not hatch at all times, but only when they 

 were taken from the storage and placed in certain 

 conditions. Whenever leaf-food was ready, then 

 the eggs could be brought by slow degrees to a 

 warm and still warmer temperature, till 70 F. 

 was reached, at which temperature they would 

 hatch in three or four days. 



The particulars of this wonderful secret is not 

 given in any of Colonel Brady's writings, that I 

 have yet seen. Neither is it generally known 

 that such a secret has been discovered; as the 

 books what few there are written on this sub- 

 ject speak of the silkworm season as only one 

 small portion of the year. 



In another chapter in this book I will give a 

 slight account of my experiments, and the results 

 that followed. 



The adaptation of Australia to silk-culture 

 was fully demonstrated by the quality of cocoons 

 and the silks that were there produced. 



After more than twenty years' faithful work 

 and of scientific experiments, Colonel Charles 

 Brady induced the government of the colony to 

 take hold of the silk business. They seemed 

 more inclined to benefit their own country by 

 the development of silk, than to spread abroad 

 the knowledge acquired at such cost of time and 

 patient experiments.
