It is wonderful how many questions will be asked by the pupils during the progress of their garden work which will often stag- ger the best teacher. Such familiar phe- nomena as the growth of stems upwards, the roots downwards, and the branches horizon- tally, will be brought forcibly to the minds of the pupils who will undoubtedly ask for an explanation.
