Sir

I have enquired about the Hot Walls done by Geo Robson Junr for Sir Wr Blackett at Wallington, as you desired; & find that the price was ten pence a Square Yard. that there were Flews of ten Inches in Width in the Middle of the Wall – that the Covers of the Flews were of Flags prepared by the Mason, but laid on by Robson – that on each Side of these Flews the Walls were five Inches in Thickness.  that the Flews were plastered in the inside. that the Bricks were led to him, & that the Lime Sand & Water were also led to him, but he made them up & paid all labourage & that the foundation was six a Yard. I am etc    HR
