Derrick"s deposition is preserved in the "Constitution Book" of Guildford. On Monday, 17 January 1597 (Julian date and thus 1598 by modern reckoning), he bore written testimony as to a parcel of land in the parish of Holy Trinity in Guildford which, originally waste, had been appropriated and enclosed by one John Parvish to serve as a timber yard. This land, said Derrick, he had known for fifty years past and:
Being a scholler in the ffree schoole of Guldeford (founded 1509), hee and diverse of his fellows did runne and play there at creckett and other plaies.
John Derrick was then aged 59 and his testimony confirms that cricket was being played by children in Surrey c.1550 and it is perhaps significant that cricket is the only one of the "plaies" referred to by name.
Derrick was a coroner and so it must be assumed his deposition was accurate.
