What kind of Japanese is this?


I am looking at a Japanese map of the early 19th century. It contains a
printed comment that I am trying to find translation for. It does not seem to
be modern Japanese so I am wondering what kind of (outdated?) Japanese this
is. (See Image)

This is 漢文{かんぶん}, a mimicked Classical Chinese. Now few Japanese can write in
this style. However, this style is still taught in high schools in Japan. In
the mandatory classes, the students do not learn the Chinese pronunciation.
Instead, they pronounce the 漢文{かんぶん} sentences as Japanese sentences. They
shuffle the characters, put Japanese words besides the Chinese characters and
fill in additional カタカナ in order to turn a Classical Chinese sentence into a
Japanese sentence. The first two sentences in the image would be read
`本邦{ほんぽう}ノ輿地{よち}ノ圖{ず}。其{そ}ノ起{おこ}リ蓋{けだ}シ中古{ちゅうこ}ニ在{あ}ル歟{か}。` Notice that the
position of `在` moved in the second sentence. These shuffling techniques are
called `訓読{くんどく}`. The writing style 漢文{かんぶん} and the reading technique
訓読{くんどく} have been present for at least 1,300 years.

This 漢文{かんぶん} style is different from 万葉仮名{まんようがな}。 漢文{かんぶん} tries to follow
the Classical Chinese grammar. In the 万葉仮名{まんようがな} style, no serious efforts
are made to follow the Classical Chinese grammar. 万葉仮名{まんようがな} is a liberal
technique to use the pronunciation of Chinese characters for denoting Japanese
pronunciation. However, in the 万葉仮名{まんようがな} technique, there are no efforts
made into following the Classical Chinese grammar.
