DOCTOR HEATH AT HOME.

Doctor Heath and the detective went in silence down the wide shrub-bordered walk, to the spot where the doctor's horse awaited him. Here the detective paused suddenly and listened a moment.

"We should not be seen together," he said in a low tone. "Do you mount your horse and ride on slowly, I will follow."

"But——"

"No buts; I can follow you, never fear; that's my business; do you go straight home and prepare to admit me on the quiet. Stay—have you any gelatine?"

"No."

"Any plaster of Paris?"

"No."

"Any wax?"

"Only a small quantity."
