 through, Ited liluff May 1, and was first seen at JJaird about the uiiddle 

 of the month. The first nest was found May -0 at tlit^ latter placa It 

 was a symmetrical structure of dried grasses and tlui outer <;overing or 

 bark of certain species of reeds, the whole being so wiihered and bleached 

 as to present a uniform grayish a[)pearan(;e. There was no lining, and 

 as the eggs had not yet been laid it is not unlikely that it was an un-

 substances in its composition, it was attached to the twigs of a low 

 shrub, among some l)owlders near the river.
