"poor sailors / early works to 1800" » "two sailors / early works to 1800", "some sailors / early works to 1800"
"poor soils / early works to 1800" » "poor souls / early works to 1800", "proper soils / early works to 1800"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"poor sailors / early works to 1800\") OR (\"poor soils / early works to 1800\"))".
• Removing quotes may allow a broader search: (( poor sailors / early works to 1800 ) OR ( poor soils / early works to 1800 )).
• Adding a wildcard symbol may retrieve word variants: (("poor sailors / early works to 1800") OR ("poor soils / early works to 1800"))*.
