This book contains a register of the boys' attendance at Station, the time allotted for sport every afternoon, unless the weather was bad.

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.
