What does the quote "time is to history as space is to geography" mean

The comparison implies each statement is as poignant as the other:-

'time is history' - every moment of time (seconds, minutes etc) passes and we cannot reclaim it, the best we can do is reflect and as we do, our understanding grows...

hence the similarity in

'space is to geography' - again, we have no control in the understanding - what we think we understand grows bigger/wider and more confusing every time we study it.

Happenings (time and space) grow bigger, more distant and more fascinating constantly, we have no control over it and must accept it .

hope that helps :-)

the california missions began in the late 18th century as an effort to convert native americans to catholicism and expand european territory. there were 21 missions in all, lasting from 1769 until about 1833.   the missions were built by the spanish starting in 1769 in order to “colonize” the territory of alta california. so the missions were important because they were the means of settling california. it also wanted to keep other european countries out of alta california. building settlements along the coast would them meet these goals. missionaries wanted to convert the indians to the roman catholic faith. california indians did much of the work to build missions.

5) as indians revolt gained power, people found additional reasons to protest against the british rule. princely families joined the uprising due to changes to the inheritance law which made adopted children ineligible to assume the throne. this was an attempt by the british to control royal succession in the princely states that were nominally independent from the british.
