I can never get my work finished lately, and I am dissatisfied with that of it which I can get done. Must make new arrangements. Invited Markie for to-day and made great preparations, but he could stay only ½ hour after all my trouble. I only showed him some slides. – I have no trust in myself at all, and never can tell whether I am getting on or going backwards in my examination music. Went and bust the lights in the lights in the top storey, by unknowingly breaking the bulb, and then switching it on. Short circuit followed. Páp swore I would never put on magic lantern again.
