*[[Jaques, George]], February 1851, “Trees in Cities” (''Magazine of Horticulture'' 17: 50–52)
:“I propose, at present, to speak first of planting trees upon side-'''walks'''. In American cities, it is customary to construct streets with a wide carriageway in the middle, and a ''walk'' for pedestrians on either side. Trees are usually planted on the line between these foot-'''walks''' and the carriageway. . . .
