well something has clearly gone awry with the yahoo server
since this message 12605 arrived with no message but only backup
& 2 of my earlier posts are either lost or suspended in ether
& who knows what else is pending or screwed up
but i will try to break thru by answering this & your following
question
from the bible
first on page 28
quoting from the 1848 peace treaty of guadalupe hidalgo
it says
1 marine league due south of the southernmost point of the port of
san diego
according to an attached copy of the 1782 pantoja map published 1802
etc etc

Purchase

& then on page 29
quoting from the gadsden treaty of 1853
it simply indicates this line was agreed to reach
from the intersection of lat 32 deg 20 min & long 111
to a point on the colorado river 20 english miles below the junction
of the gila & colorado rivers
also i believe the main point of this purchase was to facilitate a
southern transcontinental railroad
so no surprise to see it following the transport corridor
so it seems both of your surmises are right on the money
now lets see if this try gets thru the yahoo
