The mason’s gavel, the chisel and the folding rule are the tools of the apprentice. With this he can edit the rough stone he is.

For as the artist, by the aid of his instrument, gives form and regularity to the shapeless mass of stone, so education, by cultivating the ideas and by polishing the rude thoughts, transforms the ignorant savage into the civilized being.
