ELEMENTS OF AGRICULTURAL CHEMISTRY AND 
GEOLOGY. 
By JAS. F. W. JOHNSTON, M. A, F. R. SS., L. & E. 
HONORARY MEMBER OF THE UOTAL AGRICULTURAL SOCIETY OP ENGLAND, AND AUTHOR OF ' L LECTURES ON AGRICULTURAL CTTElTISTr.r AN'D GEOLOGY." 
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 onr libraries, but. 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 as, it is 
believed, no other book supplies."

THE ELEMENTS OFAGRICULTTJRI 
A BOOK FOR YOUNG FARMERS. 
By GEO. E. WARING, Jr. 
AUTHOR OF "DRAINING FOR PROFIT AND DRAINING FOR HEALTH, " FORMERLY AGRICULTURAL ENGINEER OF THE CENTRAL PARK IN NEW TORK. 
The place that this book is intended to fill is occupied hy no other work. It ia not an agricultural chemistry, nor is it a hand-book of the processes of every-day farrnin™ ; 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 which 
practical experience has proven to be of practical value.

EARTH CLOSETS: 
HOW TO MAKE THEM AND HOW TO USE THEM. 
By GEO. E. WARING, Jr. 
It is snfliciently 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 be 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 onr fntnrc prosperity. Supported ns the arguments in this little work are by the most imperative agricultural and sanitary considerations, it is believed that they will 
commend themselves to the approval of all, in both town and country, who have the well-being of society at heart.
