 B. orndta^i?). — B. Quesnelidjia^QuesneVia. — B. Thodocydnea=

 particularly to various kinds of Convolvulus. 



BIOPH'i^TUM (life-plant, some of the species being 

 sensitive to the touch). Oxaliddcese. Oxalis-like peren- 

 nial herbs, sometimes grown under glass as curiosities:

BIRDS. The horticulturist has the opportunity to 

 avail himself of a mighty band of helpers in the birds. 

 It seems not to be understood that it is perfectly pos- 

 sible for a bird to be eating something useful to man 

 at some particular moment, and at the same time to be 

 spending by far the greater part of its time eating 

 things that are harmful to man, for which service it 

 should be carefully protected. Very thorough studies of 

 the food of birds have proved that the great majority 

 are helpful to one who raises crops. Most birds are 

 l)cneficial most of the time, and very few have no re- 

 deeming traits in this regard. Moreover, if useful birds 

 are protected at all times, so as to encourage the natural 

 increase, they will do their part in an emergency, such 

 as an invasion of insects. Aside from these economic 

 reasons for bird-protection is the gain that comes from 

 their presence as attractive and interesting objects in 

 n;iture, as much to be desired as blossoms and gardens. 



It is said that there is less need of birds now that 

 insects are being destroyed by arsenical sprays. This 

 is perhaps to some extent true, but even in fruit-planta- 

 tions tlie birds are still effective; and there are hosts of 

 insects that are not effectively held within bounds by 

 the sprays. Spraying will never take the place of birds. 



Protection of birds from their enemies. 



Birds should l)e both i)rotected and attracted. Men 

 and boys with guns and shng-shots, cats, and the Eng-
