BIRD BOXES AND SPARROWS.

Those who are investigating their bird boxes, ready for new homes, will find that in some of the older ones the holes are enlarged ; and it is odds in many gardens that the sparrows will drive out the more desirable tits. A number of people have on this point taken the advice of no less a person than Henry Ford, who described in his book, My Life and Work, how they solved the question in his sanctuary by hanging boxes so that they swayed in the wind. The sparrows could not endure this, and the tits almost liked it. My own expe- rience is that all birds like a firm site ; but there are species of European tits which build pendulous nests, and Henry Ford, who is a genius at detail, seemed sure of his facts. What is the experieLe3 in the thousand sanctuaries of England, where every other garden has its nesting boxes ? Will tits and not sparrows build in swinging boxes ?
