itive detriment; and the only reason it is put 

 in is because it cheapens the lead. If, on 

 the other hand, after making the test as 

 above, you find no chalky residue in the 

 bottom of the can, you may feel pretty sure 

 that your lead is pure, or, at least, has noth- 

 ing worse in it than an addition of zinc, 

 which will not hurt it. Genuine French 

 ocher, on the other hand, combines perfect- 

 ly with the lead or zinc, and leaves no re- 

 sidue. 



There is another very simple test, though 

 perhaps not so positive in its results. Dip 

 your thumb and finger into pure white-lead 

 paste and rub them vigorously together for 

 four or five minutes. If the paint is made 

 of pure lead and linseed oil, a rubbing of 

 the fingers for four or five minutes will still 

 leave only a oily residue. If, on the other 

 hand, the paint is adulterated with barytes 



machine when at the Albany convention, 

 and was very favorable impressed with the 

 machine. The cut "and description make 

 every thing plain. 



" The engraving herewith illustrates a re- 

 versible honey-extractor made and patented 

 by E. L. Goold & Co., of Brantford, Ont. 

 It can be made either as a two-frame or 

 four-frame machine. For a two-frame 

 Langstroth a can 233^ inches in diameter is 

 required ; for a four-frame the diameter 

 must be 27 inches. The baskets are reversed 

 by means of a positive lever motion. The 

 levers radiating from the center shaft work 

 in a slot in the bottom of the comb pockets. 



Reversing the crank reverses the center 

 shaft, which in turn revolves the levers a 

 little way, and thus causes the pockets to be 

 swung around.

or lime, two or three minutes rubbing will 

 reveal a sort of dry powder between the 

 thumb and finger. Linseed oil combines 

 perfectly with lead, zinc, and ocher, but 

 it will not combine with lime, barytes, 

 or chalk, and hence the fraud is easily de- 

 tected." 



A Reversible Honey Extractor. 

 R. F. Holterman, "bf Brantford, Canada, 

 has sent to A. B. .J. the following illustra- 

 tion and description of Goold's Reversible 

 Honey Extractor. I saw a model of the 



Unlike the Stanley extractor, when one 

 pocket reverses, all must reverse. This is a 

 great advantage. 



The extractor has been in the hands of 

 Goold & Co. for over a year, their object be- 

 ing to thoroughly perfect it before giving it 

 to the public. It was carefully tried by some 

 customers and myself in the apiary last year, 

 and several changes have been made since its 

 first invention. 



The machine took the first prize at the 

 Toronto Industrial Exhibition last Fall, for 

 the best and most practical invention not 

 heretofore shown at that exhibition. There 

 were five inventions competing."
