MtCHINE roR MAP DRAWING.
New Device That Is to he Used by the
Engineer Corps In Cuba.

A new machine that looks something like n
bicycle is to be- used BY the Engineer Corps of tho
Army for map making purposes in Cuba. Two
wheels, each over three feet in circumference
tic rear one following in the track OF the other
work the mechanism Of the machine. As three
soldiers push tile machine forward the map il
drawn automatically. showing the compass dlrcc-
ton Ui the route IrnvefSed and also the differing
levels along the route. for line indicating aiti.
tud. will show change Of fifty feet IN level for
every inch recorded on the paper The machine
rs called an orogrnph, because IL records these
differences In level.
In will do what il claimed for IT, IL will make a
route survey for more rapidly than IL could be cor.
rird ont IN any other way. and a com binatiun II
these surveys vii! give u fairly npproSi mate idea
Of the lay oi the land. The machine will thus
serve the purposes Of topographic map making,
and the maps produced will be more accurate
than god many pioneer maps, and Will serve
the needs Of Tive regions mapped fairly well Til in
time they are supplnnted by scientific Topographic
maps based upon i-.Gonometrical surveys
