Hat case ran from Silver Street to Warren Street. Silver Street was parallel to Burleigh Street >From the Royal Commission on the State of Large Towns 1845. (In Sunderland) "there is a narrow, confined place called the Hat Case, leading from the street to the Old Customs House, the wall of which blocks up the avenue and intercepts the free current of air. In No 10 there is a yard in which there is a most offensive midden, rented to a man for 9d per week and cleaned out - he says - every 8 or 10 weeks, but to all appearance never entirely emptied, being as we afterwards found out, the chief depository for all the abomination in this neighbourhood and one which is cried out against as a great public nuisance. The privies of the factory houses empty their contents into this dunghill. Stinking stagnant water has no outlet from this row in which human ordure and other disgusting objects are so thickly deposited that one can hardly step clear of them! ".
