More About the Dunlop Range at Richmond Hill, Canada 



THOSE of you who hap- 

 pen to know the ex- 

 posed, tempest swept 

 locations of both the Thomas 

 Roland and Wm. Sim. Lord 

 & Burnham big houses, near 

 Boston, have a good idea of 

 the tei-riflc wind pressures 

 Mr. John H. Dunlop's houses 

 have to stand at Richmond 

 Hill, Canada. Twice have bi- 

 houses of his neighbors blown 

 down. Glass breakage from 

 vibration is a source of con- 

 stant expense to them. 

 Last Winter when one of 

 these houses went down, a 

 gale averaging 80 miles an 

 hour, and at one time reach- 

 ing 105, hammered and shoved 



against the two L. & B. iron 

 frame houses without an im- 

 pression. Scarcely any glass 

 was even cracked — none loos- 

 ened. When you think that 

 these houses were hit broad- 

 side by the gale, it's prac- 

 tically impossible to form any 

 idea of the tremendous pres- 

 sure they were under both on 

 the exposed side; and the suc- 

 tion strain on the opposite 

 side caused by the vacuum 

 formed by the wind passing 

 with such rapidity and force 

 over the ridge. We believe it 

 to be the most severe test our 

 big houses have ever been 

 subjected. We tell it to you 

 as a matter of convincement. 



The columns are ilouble steel angles, riveted together.
