lands required 350 rangers, the expense being- met by the li- 

 censees. 



Two white pine berths, each of 258 square miles, on the Jocko 

 river, were sold at the record bonus prices of $13.26 and $12.10 

 per M feet, in addition to $2 dues. A distinct advance was made 

 in these sales in that the contracts contained a clause requiring 

 the purchaser to dispose of the lumbering debris as directed by

These two little booklets are the latest addition to the Cam- 

 bridge Manuals of Science and Literature, some 60 now, which 

 enable busy workers in other fields to keep au courant with scien- 

 tific subjects outside of their sphere under guidance of trust- 

 worthy specialists without danger of too much popular or too 

 much scientific pabulum being ofifered. 



The contents of The Earth are fully described in the title. 

 The volume on the Atmosphere does not, as one might be in- 

 cHned to think, lead in the direction of Meteorology, but discusses 

 the chemistry and physics of the atmosphere, after some inter- 

 esting chapters on the history of the development of our knowl- 

 edge of the air.
