to secure several living sapsiickers, to cut them 

 off as completely as might be practicable from 

 insect food, to feed them if possible upon con- 

 centrated maple sap, and to see whether a diet 

 of that kind would sustain life. It was possible 

 that they might refuse to eat anything, that they 

 might eat the offered food but die in a few days, 

 that they might live for a time but show distress 

 and inability to digest the food. On the other

 to the diet, thrive upon maple syrup, and live for 

 weeks, perhaps months, in a manifestly healthy 

 condition. I had confidence enough in my pre- 

 vious observations to believe that the birds would 

 relish syrup, and would live upon it for a suffi- 

 ciently long time to induce those who still consid- 

 ered the birds insect eaters only, to admit that a 

 contrary presumption had been raised. 



It was first necessary to secure the birds. Hav- 

 ing failed, in 1890, to catch old birds by making 

 them tipsy, I decided to secure a nestf ul of young- 

 birds before they took to the wing. Searching the 

 forest near Orchard No. 1, 1 found, on July 1, a

 scarred the trunk. The parent birds came fre- 

 quently to the tree, and their arrival was always
