You are to clean the Reflectors and the panes in the windows every day the proper manner of cleaning the Reflectors is to take off any Oil or Smoke that may be upon them with soft tow and then rub them with a soft linen rag and Spanish white of finely powdered chalk till they are perfectly bright this must be strictly attended to or else a great part of the effect of the lights will be lost.
You will light the lamps every half an hour after Sun=set(t)ing and keep them burning till half an hour before Sunrising every day for which purpose you must attend them every two or three hours
throughout the night to help any of the lights that may be turning dim but you must take care not to stand before the lights any longer than is necessary for that purpose and you are to observe that in stormy weather you must not leave the light room the whole night and if any panes shall break you are to shut up the space immediately with one of the blanks left with you for that purpose and in the morning replace it with one of the spare panes.
In Close weather the lamps will be better for having the door that leads in to the Light room left open to give them more Air.
