These ledgers were created by the Heads of House and record events which happened within the House. They contain details of societies, sports, punishments and anything the Heads thought noteworthy of recording.

This ledger, kept by the Head of House, contains the rules and customs of Grant's House and a continuation of the names of Heads of House. There are also details of sporting achievements, the 'House Chronicle' which states what has happened in the House during the last term, and anything which the Heads thought interesting to record. A list of those tanned and what they were punished for, and an account of the Play Supper for each year is also recorded. Towards the end of the ledger are inserts with instructions of what to do in the event of an evacuation and air raid. It is accompanied by a description of the boys being evacuated to Lancing. A continuation of the last entry can be found at the start of the next ledger.

This ledger was begun in 1925 by C. E. W. Lewis (G 1920-1925) and was kept by successive Heads of House Water in which they recorded details of rowing events and achievements, those who received the house colours and anything they thought interesting or noteworthy. There are details of events in 1924 at the beginning and some entries include comments on the crews. At the end of the volume is a list of previous Heads of House Water from 1919, as well as lists of which Houses won various rowing events from c. 1922. An insert at the front of the book states that an Old Grantite, R. P. Adler (G 1922-1926), passed the book onto Grant's House.
