NOXIOUS AND VALUABLE AMMALS. 



Whenever any thing is presented to us which has apparently been 

 the result of careful study, but which we do not understand, the first 

 question we naturally ask is, " What is the use of it ? " — " In what 

 manner is it calculated to promote or disturb my interests ? " There 

 are many, into whose hands the foregoing Report may come, who will

 sources of revenue, or the means of averting damages. For such, I

 coal, marble, and all other limestones, those valuable minerals which

 solid structures ; while the monsters of olden time, the mammoth, 

 mastodon, and gigantic lizard are of rare occurrence.
