204 THE FRUIT GARDEN 



How TO Secure a Supply of Water. — An abundant supply of water is 

 most essential to successful tomato culture under glass. An economical method 

 is to build a tank at the lower end of the block of houses into which all the 

 rain which falls on the roofs may drain. A tower must be built (on which 

 to fix the tank), high enough to give the necessary pressure for expeditious 

 watering. A pump worked by hand, or by whatever power decided on (this 

 will depend on the size of the establishment), would have to be fixed for 

 pumping the water to the top of the tower. It need scarcely be said how 

 much better in every way, and how much more conducive to the success of 

 garden crops of all sorts, is rain than spring water. Therefore, means should 

 be provided to save all that falls upon the roofs. When this supply is inade- 

 quate, and no other source available, a well must be sunk.
