Here at the end of the year, I am as far from having a resting place, as ever, which is a pity for Olga and the childrens’ sake. Christmas Day was spent by all of us at Longparish House, Longparish near Whitechurch, an old Elizabethan house, standing very low, the Test flowing about 100 yards from it.
Mrs Tippinge rents it from her Grandson Ryves Hawker, who is at Eton. A nice boy. Olga and Lou stayed there a week. I could only get away for Christmas and Boxing Day. [The Tippings had rented it for many years re the Census]
