AN INDEX OF INDEXES. 



The young student may begin with the conviction that some- 

 thing of value has been written about everything, if it can only be 

 found. To find it is the difficulty, and to overcome this difficulty 

 so many indexes of different kinds have been made, that now the 

 student needs a catalogue of indexes. It is true that those boys 

 and girls who live in the country, away from large cities where the 

 large libraries are, find it very difficult to get hold of the books 

 they need, even when they know their names. Quite likely some 

 of the Agassiz Chapters might make an arrangement such as they 

 have in Australia, where the great libraries in Melbourne and the 

 other large cities have a branch office in each of the little towns 

 for hundreds of miles around, and send boxes, made for the pur- 

 pose and filled with the books called for, every week or two weeks, 

 to these towns by rail, so that the country people have almost as 

 much good of the big libraries as those people who live in cities. 

 Of course they contribute to the big library some money, but they 

 have a great many more books to select from than if the same 

 money was spent on a little home town library.
