Four postal Covers 1890's Carver, MA postmarks to Roxbury

Here are four postal covers with Carver, East Carver, and South Carver postmarks, sent to a Mrs. Albert Partridge of Roxbury, MA (Roxbury Station postmark on back of two). The bottom left letter has water stains, the bottom right is a little crinkled, but the top two are very good. Of course, two of the letters are little ones that are discouraged today. Three of the covers date from 1888-1889, one is in the 1890s.
