formation about their actual drafting or 
who drew them. I suspect that in the 
early days drafting was usually done by 
the skipper, but later on it might have 
been done by a bright midshipman. 
And of course the voyager might bring 
home sketches and notations that a pro- 
fessional would then convert to a map. 
These gentlemen and their products are 
not neglected; we learn about Abraham 
Cresques, Martin Behaim, Gerhard 
Mercator (plenty about him), Martin 
Waldseemiiller, and the Cassinis — fa- 
ther, son, grandson, great-grandson, 
and many others. 
We also learn about the invention 
and development of triangulation, the 
measurement of arcs of meridians (to 
reveal the true shape of the globe), and 
the origins of the compass, astrolabe, 
sextant, theodolite, transit, and a host 
of other instruments. John Harrison’s 
invention of the chronometer (thereby 
solving the problem of measurements 
of longitude at sea) is a particularly fas- 
cinating story. In the eighteenth cen- 
tury, in 1779, the Cassinis completed 
the mapping, by triangulation, of 
France. In the United States the heroes 
of surveying and mapping were Mason 
and Dixon, Lewis and Clark, Powell, 
Maury, and Ewing. 
The first half of the book ends with 
the international agreement to collabo- 
rate on a “one-millionth” (sixteen miles 
to the inch) map of the world. The sec- 
ond half is devoted to the twentieth cen- 
tury and the astounding inventions that 
have revolutionized surveying and 
mapping. These include the airplane, 
specialized cameras, deep-sea drilling, 
bathyscaphs, lasers, tellurometers, so- 
nar, radar, satellites, and automated 
surveying and mapping. This is exciting 
stuff and well told. Wilford had an 
enormous amount of homework to do 
and mastered it handsomely. The only 
weak spot to my eye is the four-page 
section on map projections. It lacks or- 
ganization and misses the interrelations 
of projections entirely, but it is accurate 
as far as it goes. 
Each of the four sections of The 
Mapmakers is preceded by a short epi- 
sode of a recent expedition that sur- 
veyed the Grand Canyon with the latest 
gadgetry, including helicopters, walkie- 
talkies, and a distance-measuring in- 
strument loaded with telescopes, laser 
beam generators, computers, and so 
on — price, $18,000. The author was 
present on this trip as a modem reincar- 
nation of a “chain carrier” (surveyor’s 
assistant), and the experience no doubt 
intensified his urge to write this book.
