STATE OF DISEASE IN THE BROOD. 93 



and from six months to two years more before it 

 terminates fatally.* 



Mr. Quinby says that hives " in which the disease 

 has not advanced too far will generally swarm." I 

 have had no experience in this particular, but think 

 it unlikely that many swarms or much surplus honey 

 will ever be obtained after the disease is once seated. 

 Mr. Langstroth says : " There are two species of foul 

 brood, one of which the Germans call , the dry and 

 the other the moist or foetid. The dry appears to 

 be only partial in its effects and not contagious, the 

 brood simply dying and drying up in certain parts of 

 the combs." 



From numerous examinations which I have made 

 of diseased hives imported into California during the 



* This opinion was founded on the following experiment : In 

 the month of February, 1860, upwards of one hundred hives of 

 newly jmported bees, most of them diseased, were placed within 

 one hundred rods of a stock of thirteen full and" healthy hives. 

 Honey from the dead and weak hives of the former being exposed 

 within the reach of the latter, they immediately appropriated it 

 to their own use, thereby planting the seeds of disease, which, 

 however, did not develop itself so as to be discernable till in May, 

 being about three months from the time they obtained the infected 

 honey. Several other instances of the disease being contracted 

 in like manner have also come under my own observation, each 

 tending to confirm the above idea of the time between the infec- 

 tion and the development of the disease. 



Since the above was written, a case has come to my knowledge 

 where infected honey was said to have been obtained and the 

 disease developed within six weeks ; this occurred during July 

 and August, 1860, yet it is possible that the disease in this case 

 was communicated at an earlier date.
