Docketed “With copy of experiments with Myrtle’s boiler. No advantage from lowering the bridges. Men busily engaged packing Sclessin and Danube materials. Expects a reinforcement to the coppersmith establishment in Pemberton’s son and brother. Observe Danube Co. want a pair of 60 horse engines – have a light pair 3 feet 6 inc stroke – but an estimate of regulars was sent in June last which is a reason for adopting them, and to bring in the boiler same as Soho’s.
