The United States is fortunate in the native fruit supply, including as it does so many degrees of latitude and longitude with the differences in altitude, climate, and soil needed by different varieties. Now that we count Porto Rico among our possessions, a list of our fruits would include most of the varieties known in the temperate and semi-tropical zones. The United States Department of Agriculture experiments with new varieties from foreign lands that may make themselves at home in our soil, and work like that of Luther Bur-bank produces new species. Scientific methods of fruit growing are becoming more common, and the quality of fruit will doubtless improve in spite of fungous diseases and injurious insects. Our wild fruits are not yet entirely rooted out. The Maine blueberry, for example, is found on hundreds of acres and needs no cultivation beyond burning over every third year.

Fruit is necessary in our diet, and is not an extravagance unless we buy fancy varieties brought from a distance, or native fruits out of season.
