TSE BUiJ-KiJEPE^S' REVIEW. 



101 



crating and sorting of honey will be done 

 there instead of in a separate honey-house 

 at one end, as I first intended ; and my ad- 

 vice to any one thinking of giving a house a 

 trial, would be, not to build too small. Don't 

 be cramped or you won't ever be suited with 

 it. 



In conclusion I might n^me a few of the 

 advantages of a house-apiary, but as Mr. B. 

 Taylor has done so well in his articles on 

 pages 324, 325, 32(5, of December Review, I 

 will only add that I indorse every word that 

 he says in favor of them, only he does not 

 praise them enough. 



Swarming did you say ? Oh ! yes, sure 

 enough ; but I must leave this for another 

 chapter, as this article is long enough al- 

 ready. But in the meantime, if you are 

 thinking of building a house-apiary, don't 

 let the fear of swarming hinder you, as that 

 can be very satisfactorily settled. I am as- 

 tonished that some of our headlights should 

 think and say that bee-keeping has reached 

 the climax of perfection, or "' reached the 

 end of the rope." Why, last year came self- 

 hivers. and next will come non-swarming 

 without extra work, and with more and a 

 better quality of honey, this I know to be a 

 FACT. Watch for it.

Some Experiments and Arguments Showing 



that Multiple Tubes do not Increase the 



Blast in a Bee Smoker. 



LOWKY JOHNSON. 



^i|»N reference to Mr. Cornell's theory of in- 

 ^ creasing the draught from a smoker, I 

 «»^ have to say that I have just completed a 

 series of experiments with his multiple 

 tubes, as illustrated in the October number, 

 page 2.59, of the Review, and find that, other 

 things being equal, there is no increase of 

 draught or blast by that means over the or- 

 dinary method of using a continuous tube 

 or discharging the air directly into the fire 

 box as in the Bingham smoker. 



A light thin board was suspended so that 

 it could vibrate freely; a blast from a smoker 

 bellows having the multiple tubes, as sug- 

 gested by Mr. Cornell, was directed against 

 this suspended board and the distance it vi- 

 brated was noted. This was done several 

 times, the board being first brought to a 

 rest each time. Each time the board swung 

 the same distance. Then these multiple 



tubes were removed and a simple continu- 

 ous tube used and the same operation per- 

 formed again. The board swung or vibrated 

 the same distance as when the multiple tubes 

 were used, thus proving that there was no 

 increase of the blast. 



Not being entirely satisfied, I again 

 affixed the multiple tubes and directed 

 the blast against the board five times in 

 succession as the board returned, and noted 

 tlie distance that it was caused to swing. 

 Then, removing the multiple tubes, I again 

 inserted a simple continuous tube and per- 

 formed the same operation and the distance 

 the board was caused to swing noted, and 

 I found it just the same as when the multiple 

 tubes were used, thus proving conclusively 

 to my mind that there can be no increase of 

 the blast by a series of tubes, one discharg- 

 ing into a larger one. 



Mr. Cornell seems to have overlooked the 

 fact that the inertia of the greater amount 

 of air in the larger tubes must be overcome, 

 together with the friction of the same. 

 While the volumeot air in motion is greater, 

 the siieed, from the above cause, is necessa- 

 rily less, so that the velocity of the air from 

 the smaller tube multiplied by its transverse 

 area is equal to the transverse area of the 

 larger tube multiplied by the velocity of the 

 air from it. 



In the case of ventilation, it is quite dif- 

 ferent from a smoker. The heated air ex- 

 pands and becoming lighter, has a tendency 

 to rise of its own accord and not from any 

 increased draught from these multiple tubes.

In this age of progress and improvement, 

 when men are cutting loose from old lines 

 and establishing new, when every day brings 

 to our ears tidings of some new discovery or 

 invention, bee-keepers may well ask them- 

 selves, "what has the future in store for us?"
