When the evening lamps are lighted, or rather just antecedent to that operation — say in the little interval which follows the retirement of the ladies from the dining-room, and precedes the appearance of the laughing sceptics below — a grain of ghost talk mingles, not inharmoniously, with the gentle domestic topics invoked by the subdued light and confidential feeling of the hour. The treatment of the subject is necessarily superficial. Twenty minutes will not suffice for a dive into philosophic deeps. Facts are simply adduced. Theme and proposition are laid bare, and left so, for any after-manipulations profounder thinkers please. Nevertheless, from the pabulum (often cxccedingly raw) supplied by these little conversations, may be deduced a whole garden of thought, worthy the attention of the most earnest sage.
