. British bee journal & bee-keepers adviser. Bees. May 6, 1920. THE BRITISH BEE JOURNAL. 217. The Use of Two Brood Chambers. We promised last week to make a few notes on the letter on size of frames (10174, p. 213) by Mr. Morris. We have not yet read any argument to cause us to alter our statement with regard to the space between two sets of brood combs hindering the queen. We have not, and do not now say the space will make no difference. How much it hinders will de- pend partly on the queen. We have more than once known queens penetrate and spoil two racks of sections, and we venture to think any queen that will do this, or even go up into one rack of sections, would not allow the space between two sets of frames to hinder her activities in the slightest degree. The matter is easily tested. Let any bee-keeper put on a super of sliallow combs without a queen excluder, and see how long it will be before the queen goes up. To carry the argument a little further, let us consider the expan- sion of the brood nest from the time breed- ing commences in the early weeks of the year. The queen will be somewhere in the centre of the cluster of bees, and will there commence to lay. The area of comb containing eggs and brood gradually ex- pands, the cells on one side of the two combs facing each other being utilised. After a time the patches of brood extend to the limit covered by the cluster of bees. Normally this cluster is spherical, and may extend over three or four combs, but will not cover them to the ends. As the brood area increases, bees from the outer combs must come towards the centre, so that the cluster becomes elongated parallel with the combs, but eventually a limit to this form of expansion is reached, and it becomas necessary for the queen to transfer her activities to the other side i;f one of the combs. How is this to be done? It is very seldom there is a bee-way through the comb, so the queen must either go over the top barâif there is a bee spaceâor
