FOREWORD 



To us, who standing by, have watched Arthur C. 

 Pillsbury's career, the element of adventurous 

 achievement has always been well in the forefront 

 of our observation. Whether, as in its early unfold- 

 ing, it took him floating alone in his Peterboro 

 canoe, through seemingly endless days and nights 

 down the dark and sullen reaches of the Yukon, or 

 skittering over flashing crests of its Rapids floating 

 airily in a tiny silken white balloon over San Fran- 

 cisco Bay "wrestling with the angels" and the Power 

 of Darkness inherent in the muck and slime of a tide 

 marsh landing, but always saving his precious films 

 or of many weary miles and days in mountains and 

 plains, gathering thousands of picture impressions 

 of the power and glory which is theirs of days and 

 years of patient laboratory exploitation through the 

 keen, undeviating eyes of his microscopes and cam- 

 eras, to bring us his progressive interpretation of 

 many of Nature's beautiful and so nearly hidden 

 ways of the fulfilling of Her design as his life's work 

 goes out through consciousness, so this record of it 

 is for all who care to know and remember.
