"Wait at the outside door," the count said. "Captain Carstairs will speak to you as he leaves."

The man bowed and went out, and the count then said, with a smile at the look of surprise on Charlie's face:

"It was not a slip of the tongue. Here is a commission, signed by his majesty, appointing you to the rank of captain, as he has long considered that you had well won your promotion, by your suggestion which enabled him to cross the Dwina without loss; but he thought there would be a difficulty in placing you over the heads of so many officers senior to yourself. This inconvenience no longer exists, now that you have what may be considered a staff appointment, and the rank may, moreover, add to your weight and influence in your interviews with persons at Warsaw.

"You will need money. Here is a purse for your expenses. You may meet with some of these men, especially among the Jewish traders, who may need a bribe. Bribery is common, from the highest to the lowest, in Poland. You will find, in this letter of instructions, that you are authorized to promise sums of money to men whose assistance may be valuable. It is impossible to fix the sums. These must depend upon the position of the men, and the value of their services; and I can only say do not be lavish, but at the same time do not hesitate to promise a sum that will secure the services of useful men. Your best plan will be to find out, if you are able, what each man expects, and to make what abatement you can. The only limit placed is that you must not commit the royal treasury to a total sum exceeding ten thousand crowns. You will, I hope, find a smaller sum suffice.

"The envoy will start at six tomorrow morning. I do not know that there are any further instructions to give you. You will find details, in these written instructions, as to the manner in which you are to communicate, from time to time, the result of your mission, and you will receive orders when to return."

Outside the house, Charlie saw his new servant waiting him.

"You have a horse, Stanislas?"

"Yes, sir, I have been provided with one. I have also a brace of pistols, and a sword."

"I hope you will not have to use them, but in these disturbed times they are necessaries."

"I have better clothes than these, sir, if you wish me to look gay."
