If now the house be piped for water by running a line 

 along the front of each bench, with an opening for each 

 section of bench, the whole house can be watered at 

 once with the opening and closing of a single stopcock. 

 The saving of labor which this change implies must go 

 some ways toward meeting the additional first cost of 

 construction. 



Of course a house that is already piped in the 

 ordinary way, with hose attachments provided, could not 

 be changed profitably, but if a house is being built for 

 this purpose, the hose can be entirely done away with, 

 and a line of pipe run along the front of each bench, and 

 the whole watering done by turning a single stop-cock, or 

 stop-cocks can be added for each one of the different sec- 

 tions, and then you have the house under more perfect 

 control. 



There seems to be but little remaining that calls for the 

 services of the Experiment Station. If it is found that 

 the Stations have done a signal service to commercial 

 horticulture, as it now appears, they ask nothing in re- 

 turn but commendation, and a support that will increase 

 their usefulness.
