her carriage, and they drive about the beautiful district of the Oranges.

Mrs. Edison has undertaken the task of keeping the inventor healthy. She will not permit him to neglect his meals, or to work more than she thinks is good for him. She insists that he shall leave the laboratory at a certain hour each night, and she undertakes to personally see that he does so. At times, Mr. Edison objects, but in a very mild way, to this régime. Not long ago, he was deeply engaged in a certain experiment, when Mrs. Edison called for him and insisted upon taking him home. After some resistance, he at last consented, saying, however, by way of a final protest, as he stepped into the carriage:—

“Billy” (his pet name for Mrs. Edison), “you’re a nuisance.”

Were it not, however, for the saving influence which Mrs. Edison exercises over her husband, it is doubtful if he would accomplish so much.
