Concatenating fields from multiple records

I have an Access table that contains records of customer notes. The notes were recorded on an AS400 green screen and the USER was presented with a series of 4 lines in which to record notes or comments. Each line represented a field with with a maximum of 50 characters. Therefore if the USER needed to make a comment containing more than 50 characters, he or she would drop to the next line and continue typing, however each line is stored as a separate record.  The attached file is a subset of the 13,000 records in the database.

My task is to concatenate all the message fields for a given date. Each date being a new record in new data table that I will create using the advice I receive here. On the attached spreadsheet I have chosen on example (yellow shading rows 28-35). Row 65 (shaded in pinkish) is the result I want. An I need to do it for 13,000 records comprised of maybe 2400 separate entities (accounts).

Any and all help will be appreciated and rewarded with a speedy award of points.
