Fig. 133. Service station gardens showing the descriptive signs placed on the plots 

 for the benefit of the San Francisco back-yard gardeners. (From Stand. Oil Bui.) 



to the Associated Charities and various other church and benevolent organizations. 

 The Standard Oil Company has done all this at their own expense and donates the 

 produce. 



Back-yard gardens have been planted everywhere and a wholesome determination 

 has entered the heart of San Francisco to do her part in producing and conserving 

 food products. While the acreage is comparatively small, still the resulting produce 

 is a large addition to the food resources of the city, for in intensive gardening the 

 principal factor is the labor devoted to the care of the gardens, and San Francisco 

 by planting back-yard gardens is devoting thousands of hours of labor to food 

 production which would otherwise be lost.
