AN EFFICIENT TYPE OF LAWN SPRINKLER 
THE BOSTON GIANT PARK SPRINKLER IN OPERATION ON BOSTON COMMON. 
One of the most exacting duties of the 
summer season in large parks and ceme- 
teries is the sprinkling and irrigating of 
the lawns. In a dry season it is a very 
difficult problem to provide the immense 
stretches of lawn with enough water to 
keep the grass and other vegetation in 
thriving condition. 
Where the work is done by hand and 
small sprinklers, lawn sprinkling is a mat- 
ter that requires individual labor and atten- 
tion that makes it one of the most expen- 
sive duties connected with lawn mainten- 
ance. 
Various types of mechanical sprinklers 
have been utilized to assist in covering 
larger area and eliminating individual labor 
as much as possible. 
One of the most powerful and useful of 
these is the “Boston Giant Park Sprinkler,” 
that has been successfully used for several 
seasons in the parks of Boston and other 
large cities. 
The need for an efficient sprinkler to save 
the grass of Boston Common a few years 
ago first brought the Boston Giant sprinkler 
into prominence. It was decided that heroic 
action should be taken to save the 600 Com- 
mon trees and to insure a healthy growth 
of grass that would withstand the dryest 
summer season. Olmsted Brothers, the 
landscape architects, were directed to lay 
out the plan of campaign. The first prob- 
lem was that of meeting the excessive dry- 
ness of the soil. Sub-surface irrigation ap- 
pealed to the authorities as perhaps the only
