[9205] On page 427 (9202) Mr. Pearman raises some very interesting points. One at leaist I will endeavour to answer, namely, " Can anyone with experience say how soon bee paralysis will show itself after it has been known to have been introduced into the hive? " I think he will give me the credit of having the necessary qualifications, , experience. Therefore, I wish to say that I have nev^er known a case to develop in less than four months. Usually, it takes a year, and often longer. To prove this it has been demonstrated by hiving swarms (known to be abso- lutely healthy) on to combs that diseased bees have previously died on. Secondly, by making an artificial swarm of a healthy stock and giving it diseased combs. In the third place, by making an artificial swarm of an infected stock showing crawlers, destroying the swarm, and watch- ing results on the old stock which has young bees and eventually a yoiing queen. In this last case it is surprising how long the disease is in showing itself again. I therefore ask my friend to look back and see if he cannot find something, even the slightest clue, which he has overlooked in placing the period as low as three weeks, remembering that this disease mostly develops in the late summer and autumn. He also opens up another important matter which I think should be cleared up right away. It is quite easy, after the expert has paid
