78 BORDER LINES OF KNOWLEDGE 



It is time to bring these crowded remarks to a close. 

 The day has been when at the beginning of a course of 

 Lectures I should have thouo-ht it fittino; to exhort 

 you to diligence and entire devotion to your tasks as 

 students. It is not so now. The young man who has 

 not heard the clarion-voices of honor and of duty now 

 soundino; thi'ouo-hout the land, will heed no word of 

 mine. In the camp or the city, in the field or the 

 hospital, under sheltering roof, or half-protecting can- 

 vas, or open sky, shedding our own blood or stanching 

 that of our wounded defenders, students or teachers, — 

 whatever our calling and our abihty, we belong, not to 

 ourselves, but to our imperilled country, whose danger 

 is our calamity, whose ruin would be our enslavement, 

 whose rescue shall be our earthly salvation ! 



You cannot all follow the armies of your country to 

 the field. But remember that he who labors for the 

 general good at home is an ununiformed soldier in the 

 same holy cause with those who bear arms or minister 

 at the side of the ambulance and in the camp hospital. 

 Larrey claimed no precedence of Dupuytren, nor 

 Guthrie of Sir Astley Cooper. As for the nobleness of 

 the task for which you are preparing yourselves, I do 

 not know that I can speak of it more strongly in prose 

 than I did in the peaceful times before these days of 

 trial, in the form of verse, and I will so far trespass 

 on your time and patience as to close this Lecture by 

 reading you
