Mary Louise Greene made the case for the teaching of gardening to city children:
Perhaps best of all is that the teaching of the saner and sweeter side of life which comes when the school garden takes the child off the city streets, away from crowded alleys, vicious surroundings...when it finds happy work for idle hands, health for enfeebled bodies, and training for the will and affections.
