meeting — that the committee have carefully examined the same, 

 and from the statements made and certified by B. Gifford, it ap- 

 pears to be a valuable discovery. The results of the experiments 

 made the last year, are truly wonderlul, and if on further trial it 

 should prove equally satisfactory, Mr. Stockholm deserves great 

 credit for the discovery, provided he makes the discovery known 

 to the public, and will stand in the enviable position of being a 

 great benefactor to his country, as causing " two blades of grass 

 to grow where but one grew before." 



As Mr. Stockholm has not divulged the method or materials 

 with which his " chemical guano" is composed, the committee 

 cannot form an opinion of its relative value ; and as he intends 

 to prepare enough for testing its qualities the coming season, the 

 committee w^ould recommend a further trial, before an opinion of 

 its merits or demerits can be passed upon by the Society.

PUBLICATIONS. 



The American Poulterer's Companion. 



This valuable work has passed through four editions, which 

 must be regarded as substantial evidence of the usefulness of the 

 work. 



The fifth edition is much improved, both in additional matter, 

 and in the style and execution of the work generally. It contains 

 all that is necessary to be known in regard to the raising of poul- 

 try ; and as this is a branch of business which is both profitable 

 and interesting, we hope the work will fall into the hands of the 

 younger members of the family throughout our land. It is well 

 adapted to our school libraries, where w^e hope it may be placed, 

 for the general benefit of the young.
