The vernacular names of Rock vS wallow, as its generic name 

 implies, and House Swallow are equally applicable to this 

 species as that of the generally recognised name of Tree 

 Swallow. It was not met with at Coolabah, but it was the 

 first bird seen by me at Brewarrina, and as I found out after- 

 wards w'as the most common bird to be met with in the town, 

 not excepting the acclimatised and ubiquitous House Sparrow 

 (Passer domestic us). These birds 1 found were utilizing nearly 

 all the crevices and crannies in the woodwork of houses for 

 'their nests, but all seen were under verandahs, either of shoj^s 

 or places of business, or under the verandah of the balcony of 

 the Barwon Hotel where I was staying ; one nest, with young, 

 being above the French windows of my bedroom. Nearly all 

 had these breeding places in the woodwork, fashioned to the 

 birds' liking with dried grasses and leaves and outwardly 

 with pellets of mud, the shape varying according to the space 

 to be filled uj). The birds entered, and left the nests freely, 

 and it reminded me very much of a sinjilar scene I witnessed 

 about the house and stables of " Holmfirth," at the Reedbeds, 

 near Adelaide, South Australia.
