. REARING SILKWORMS. 113 



not by any means the best tree for all ages. In 

 other cases the groves were set out in localities 

 where the dust from the road in the dry season 

 rested on the leaves, and they failed to wash off 

 the dust. This proved disastrous to silkworms, 

 and very many died from the effects of dust 

 taken into the system. It also is injurious to 

 the worm to come in contact with dust externally, 

 as, their breathing apertures being numerous, 

 they imbibe freely from their surroundings. 



Both men and women of note entered into the 

 business of rearing silkworms in the British 

 colony, and with some degree of success, not, 

 however, as great as would have marked their 

 endeavors, had they gone at the business in a 

 more practical way, and, first of alL^c^uriiedr-the- 

 cost, and employed only those who understood 

 thoroughly the care of the worms and the culti- 

 vation of the mulberry.. Colonel Brady made 

 one discovery which had never before been 

 thought of, and which is of incalculable worth to 

 all countries where it is possible to carry out his 

 system. I refer to the continuous hatching out 

 of the silkworm. After long and faithful study 

 with different races and different foods, he dis- 

 covered that it was possible to have silk-eggs 

 hatch out at all seasons of the year. Next he 

 discovered that it was possible to control these
