Skewy, making glass was a complicated business,, a big brick cone is needed for starters. Sheet glass was packed in wooden cases for shipment. Canals probably gave a smoother run than road or rail.
However, the guys have established that this Brookwalls, as per the census, is a mistranscription or an error on the part of the ennumerator. The actual address is Brook Walk in Derby itself, it had to be somewhere with a glassworks.
Many thanks.
