ELEMENTS OF AGRICULTURAL CHEMISTRY AND 
GEOLOGY. 
By JAS. F. W. JOHNSTON, M. A., F. R. SS., L. & E. 
HONORARY MEMBER OP THE ROYAI. AGRICULTURAL SOCIETY OP ENGLAND, AND AUTHOR OP “LECTURES ON AGRICULTURAL CHEMISTRY AND OEOI.OGY.’’ 
WITH A COMPLETE INDEX AND AMERICAN PREFACE. 
By SIMON BROWN, editor of “The New England Farmer.” 
In his preface to this book Mr. Brown wrote:—“ The work is offered to the public, not to supersede the truly-scientific and more technical treatise of Stockhardt in the schools 
and colleges, not, indeed, to take the place of any existing work, even in Our libraries, hut as containing the matured results of a carefully trained mind, which has long compared 
the practical notions of the farmer with the theoretical ideas of the chemist and geologist, and so-wrought out a fund of valuable knowledge for practical men, such ns, it is 
believed, no other book supplies.”

THE ELEMENTS OE AGRICULTURE; 
A BOOK FOR YOUNG- FARMERS. 
By GEO. E. WARING, Jr. 
AUTHOR OP “DRAINING POR PROFIT AND DRAINING POR HEALTH,” FORMERLY AGRICULTURAL ENGINEER OP THE CENTRAL PARK IN NEW YORK, 
The place flint this hook is intended to fill is occupied by no other work. It is not an agricultural chemistry, nor is it a hand-book of the processes of every-day farming ;—only 
an attempt to translate Into common language, for the use of every-day farmers, that which science has discovered and has told in its own necessarily technical terms, and whioh 
practical experience has proven to he of practical value.

EARTH CLOSETS: 
HOW TO MAKE THEM AND HOW TO USE THEM. 
By GEO. E. WARING, Jr. 
It is sufficiently understood, by all who have given the least thought to the subject, that the waste of the most vital elements of the soil’s fertility, through our present prac¬ 
tice of treating human excrement as a thing that is to he hurried into the sea, or buried in underground vaults, or in some other way put out of sight and out of reach, is full of 
danger to our future prosperity. Supported as the arguments in this little work are by the most imperative agricultural and sanitary considerations, it ia believed that they will 
commend themselves to the approval of all, in both town aud country, who have the well-being of society at. heart.
