very little shyness but instead a great deal of curiosity, and if the observer 

 is still they will come very close to him and sing. On June 26, 1915, Dr. 

 T. S. Roberts and I saw a female with her bill full of food in the spruce 

 swamp north of Cambridge. 



12. Oporornis Philadelphia. Mourning Warbler. — A few may be 

 seen and heard singing here in summer in the second growth of rich woods. 

 This species like the last is very tame while singing and chooses some dead 

 limb in full view from which to deliver its loud song. May to September. 



13. Certhia familiaris americana. Brown Creeper. — Permanent 

 resident. A few winter in the tamarack and spruce woods where they are 

 protected from cold winds. In the heavily wooded bottomlands by " Lost 

 River " I saw a pair on June 11, 1915. The scaly bark which was peeling 

 off the old soft maples gave suitable nesting sites and the birds' anxious 

 call-notes indicated that they had a nest near by. 



14. Regulus satrapa satrapa. Golden-crowned Kinglet. — Last 

 winter (1914-1915), this bird was found to be quite common throughout 

 the cold months in the pine and spruce woods, where its penetrating " ti-ti " 

 betrayed its presence for some distance through the clear, frosty air. It was 

 supposed to be very rare and sporadic in southern Minnesota in winter. 



15. Hylocichla guttata pallasi. Hermit Thrush. — In the extensive 

 pine woods bordering tamarack swamps northeast of Grandy, at least 

 three Hermit Thrushes were heard singing this summer (1915) whenever 

 I visited that locality. This is the most southern summer record thus far 

 for Minnesota. — Lawrence L. Lofstrom, Cambridge, Minn.

Dall's Biography of Baird. 1 — Twenty-seven years have elapsed since 

 the death of Prof. Baird, and while numerous tributes to his scientific 

 attainments and achievements have been published, no biography at all 

 commensurate with his position in the development of science in America, 

 has hitherto appeared. This was undoubtedly due to the fact, well known 

 to Prof. Baird's friends, that his daughter Miss Lucy Hunter Baird was 

 engaged upon such a work with the aid of Prof. G. Browne Goode, assistant 

 Secretary of the Smithsonian Institution during her father's incumbency 

 as secretary. Prof. Goode's death and the recurrent illness and ultimate
