NATURE ON THE ROOF. 85 



stay by and adjust their feathers. He walks on, 

 giving a little chirp with his mouth, and they follow 

 him along the path a cloud about his shoulders, 

 and the rest flying from shrub to shrub, perching, 

 and then following again. They are all perfectly

 across one of these sparrow-tamers by chance, and 

 was much amused at the scene, which, to any one 

 not acquainted with birds, appears marvellous; but

 up straws in their beaks, and carrying them half-way 

 to the roof, then letting the straws float away ; and

 in good order, very little light enters, and this space 

 is nearly dark in daylight. Even if chinks admit 

 a beam of light, it is not enough ; they seldom 

 enter or fly about there, though quite accessible to 

 them. But if the roof is in bad order, and this space

 they like light. The swallows could easily go in and 

 make nests upon the beams, but they will not, unless 

 the place is well lit. They do not like darkness in
