wood, sheet Iron, and a multitude of equally diverse materials. 

 If these things be studied from the viewpoint just mentioned 

 any knowledge of those characteristics which are not intimately 

 connected with their availability as structural materials is merely 

 a collection of fugitive items without relation or connection. 

 The mind may become stored with 'a thousand wonders of land 

 and sea' but if these facts be unrelated and unconnected its 

 condition is after all somewhat comparable to that of a dictionary 

 which an acquaintance of mine described as 'mighty interesting 

 reading but powerful disconnected.' 



" Unrelated facts are of course unexplained and such a mass of 

 highly interesting information is known only in an empirical 

 way as much of it was known long before the birth of the sciences. 

 If a science is to be taught the gaps must be filled up in such 

 manner that the knowledge will be, if not continuous, at least 

 orderly. This does not necessitate the omission of the materials 

 selected from everyday life and related to human needs but it 

 does require a careful selection among these and the addition to 

 the 'practical' materials thus selected of those more practical 

 materials which are fundamental to an understanding of the field 

 and from which most of the practical scientific knowledge has 

 arisen." 



The conservation policies as established under the Roosevelt 

 administration have been strengthened by two recent decisions 

 of the Supreme Court. Both cases dealt originally with grazing 

 on national reservations. Because of the arguments brought 

 forward, the decisions do more than protect the forest reservations 

 in these cases ; they close the State's rights refuge to the enemies 

 of conservation ; and the second does away with the squabble over 

 delegating legislative power by Congress, affirming that there 

 are certain powers that Congress can either exercise or delegate, 

 and that when it does delegate these powers it does not change 

 their character from administrative to legislative by making the 

 violation punishable. 



Seven addresses on botanical teaching were made at the Min- 

 neapolis meeting in December (A. A. A. S.; Science, April 28).
