Write a note on literary style of the New England historians.

I assume you're referring to the earliest writers of the
region, which takes us clear back to Jamestown and Plymouth.  If that's so, the writers
were members of those settlements and their writings were journals and other personal
reflections.  Their common literary style, then, is personal writing to record their
histories.

William Bradford's Of Plymouth
Plantation is a journal of both the historical and spiritual journey of the
settlers of Plymouth.  It is clearly written with the intent for others to read it, so
it is a personal journal intended for a much larger audience (though I'm confident he
had no idea just how large that audience would come to
be).

John Smith's General History of Virginia
is also a journal, though it was clearly intended to make himself look good. 
He writes in an affected third person style, so the journal reads less personally (and
so he can enhance his own reputation) and more like a general narrative.  This journal
was reworked for years before publication, so its strict historic perspective has been
skewed.

Other writers of the day, such as Anne Bradstreet
and Edward Taylor, wrote more spiritual poetry which also contained glimpses into early
new England life.

All of them (poets excepted) wrote in the
English of the day, which we find difficult to read in the original (think
King James Bible, magnified). Their styles, however, were fairly
plain and readable by their standards.  These were not literary writers; these were
historians who chose to write, and they did so in their own
styles.

The overall literary style, then, was personal
reflection and historical recording.  In truth, none of the writing of that time period
is particularly artful--they were too busy trying first to survive and then thrive to
have much time for anything more literary.

Hope this
helps.
