Clearing Costs Reduced 



The recent land clearing tests conducted by the University of 

 Wisconsin have revolutionized methods and established conclu- 

 sively much lower clearing costs per acre 



The leading kinds of stump pullers — hand and power — were 

 represented. The dynamite used was 



RED CROSS FARM PO'WDER 



These tests proved the following important facts: 

 1st — The cheaper Red Cross Farm Powders will in most soils blast 

 out stumps as well as the most expensive 30% and 40% grades. 





2nd — The combined use of Red Cross Farm Powder and a stump 

 puller is often the cheapest and best way to clear land. 



3rd— Properly placed charges fired with a blasting machine greatly 

 reduce the amount, strength and cost of the dynamite required. 



As a result the average stump covered land can now be cleared at 

 less cost per acre than before the war. 



Write Now lor Full Intormation 



Every farmer with stump covered land should know the full facts 

 about this modern method of land clearing. Write today for

HOW TO KNOW THEM 



Photographs from Nature 

 By ARTHXJR I. EMERSON 



WITH A GUIDE TO THEIR RECOGNI- 

 TION AT ANY SEASON OF THE YEAR 

 AND NOTES ON THEIR CHARACTER- 

 ISTICS, DISTRIBUTION AND CULTURE 



By CLARENCE M. WEED, D.Sc.

ALL nature-lovers will hail this book 

 L with delight. Its purpose is to 

 afford an opportunity for a more 

 intelligent acquaintance with American 

 trees, native and naturalized. The 

 pictures upon the plates have in all 

 cases been photographed direct from 

 nature, and have been brought together 

 in such a way that the non-botanical 

 reader can recognize at a glance either 

 the whole tree or the leaves, flowers, 

 fruits, or winter twigs, and thus be able 

 to identify with ease and certainty any 

 unknown tree to whicla his attention 

 may be called. In the discussion of the 

 text especial attention has been given 

 to the distinguishing character of the 

 various species, as well as to the more 

 interesting phases of the yearly cycle 

 of each, and the special values of each 

 for ornamental planting.
