some dense course would be the most enjoyable thing imaginable.  Will I never be able to, study nature as I could, until, by a partial isolation or complete isolation from her, keenness of my interest will have been dulled?  I hope not, and I think not.  I have just finished Burrough’s “Locust’s and Wild Honey.”  Evidently he had most of his time to give over to his study.  I envy him.  Writing as he did, fifty years ago, he has a nature which is wilder than ours if to-day, perhaps more lovable, but broader.  I find that so many of his impressions coincide with my own.
