into a stubble field. Every few minutes a Fox Sparrow 
would begin its divine song but before it had half finished 
another would join in, then another, and still others, 
followed by Tree Sparrows until a dozen of more of both 
kinds were singing at once, the trilling of several Juneos 
coming in in the intervals like a low accompaniment. I know 
of nothing finer in the way of bird music than one of these 
outbursts heard, as I heard them to-day, with the warm 
April sunshine lighting up the brown fields and the bracing

While on our way to Concord just as we were 
entering the village of Lincoln, we saw a Broad-winged Hawk 
soaring overhead at a moderate height. Its peculiar shape 
and markings made it quite unmistakable. A little further 
on a fine old MarshHawk appeared, beating a meadow on the 
left of the road, following a ditch for some distance, 
keeping much of the time below the level of its banks. This 
bird appeared fully as white as an adult Herring Gull. 
We left Concord at 3 P.M. and returned to Cam¬ 
bridge by way of the direct road to Waltham past Holden 
Pond. Nothing of peculiar interest was noticed until just 
as we were passing the Payson place when on the opposite 
side of the road just over the wall I saw what I took 
at first for a Shrike, sitting on the top of a brush heap.
