A Maple Tree
Maples of various species are among the most attractive of our indigenous trees. They are ornamental in our parks and dooryards, some of them furnish timber of very high grade, and one of them furnishes a sap that is transformed into the most delectable of sugars. The California species here shown is chiefly prized for its ornamental qualities.
