no time will be lost, and I think if I am with you, you will be more
sure of attention from the chemist, who is a very busy man."

Jennie saw the Director did not wish to let her out of his sight, and
although she smiled at his suspicion, she answered politely,--

"It is very kind of you to take so much trouble and devote so much
