These positions being established, it might still remain to ex- 
amine the relations of geological science to the developing in- 
telligence of the young. Though this also is a field which 
cannot now be entered, it would be easy to show that many of 
the observational data of the science are precisely suited to the 
stage of intellectual development of young pupils; other data, 
and the inferential principles of the science, to pupils of pro- 
gressively maturer years. And finally, it would be easy to il- 
lustrate practically the observational method of introducing the 
familiar elements of geology to pupils of tender years, and pro- 
ceeding by gradual expansion and elevation of the method, to 
ranges of geological thought suited to pupils of full maturity. 
I leave the subject to the reader's reflections. What I have 
said is true or untrue, or partly true and partly untrue. If true,^ 
educators cannot, as reasonable persons, permit the science of 
geology to remain under their repi'oach and neglect as a ma- 
terialistic science — a "bread and butter science." They must 
act; they must acknowledge the truth, and allow geology to 
come into the enjoyment of its rights in the field of education. 
If what I have said is untrue, my positions demand an impartial 
refutation ; for a wide and powerful public sentiment is gather- 
ing at my side. If they are partly true, I shall continue to 
maintain that the true is the larger part, until my numerous and 
powerful literary friends honor my views with the electric light 
and heat of their destructive criticism.
