GARDENING FOE PROFIT. 



them off in a great measure, and what blows over blows 

 mostly off through the 

 valley between the sashes. 

 The water from the gut- 

 ter is led into a cistern, 

 at the south end of the 

 greenhouses, of a capacity 

 of not less than 3,000 

 cubic feet if 

 5,000, all the 

 better ; to this 

 is connected a 

 Douglas Force 

 Pump, figure 7, 

 with 150 feet of 

 one and a half 

 inch hose, and to the end 

 of the hose is attached a 

 heavy sprinkler. One man 

 pumps, and another reg- 

 ulates the water and 

 sprinkles it over the 

 plants. My establishment 

 in 1866 contained over an 

 acre of glass, and yet, by 

 this labor-saving arrange- 

 ment, all the plants were 

 thoroughly drenched with 

 water by two men in four 

 hours. Before adopting 

 this method of watering, at least four of the 

 hands were employed the whole day during the 

 spring months in watering, and then the work 

 was not done half so well. There is nothing 

 that I have ever done, connected with horticultural 

 operations, that has been so entirely satisfactory as this
