When the profit of these several transactions were reckoned it was found that more than $100,000 had been earned by this little fleet above all outlay. Soon after his return young Derby sailed for Mocha, an Arabian port in the Red Sea, to pick up a cargo of coffee. The natives had never heard of America, and the strange vessel was a nine days’ wonder.

In 1788 Mr. Derby decided to send a ship for a direct voyage to Batavia, another novel commercial undertaking. While the purely business side of these enterprises is not thrilling, it holds a certain interest as showing the responsibilities of the shipmasters upon whose judgment depended the results of the voyage. For this first American voyage to Batavia, the instructions of the captain and supercargo from the owner, Mr. Derby, read as follows:

“Salem, February, 1789.

“Captain James Magee, Jr.,

“Mr. Thomas Perkins (supercargo)

“Gents: The ship Astrea of which James Magee is master and Mr. Thomas Perkins is supercargo, being ready for sea, I do advise and order you to come to sail, and make the best of your way for Batavia, and on your arrival there you will dispose of such part of your cargo as you think may be the most for my interest.

“I think you had best sell a few casks of the most ordinary ginseng, if you can get one dollar a pound for it. If the price of sugar be low, you will then take into the ship as much of the best white kind as will floor her, and fifty thousand weight of coffee, if it is as low as we have heard—part of which you will be able to stow between the beams and the quintlings, and fifteen thousand of saltpeter, if very low; some nutmegs, and fifty thousand weight of pepper. This you will stow in the fore peak, for fear of its injuring the teas. The sugar will save the expense of any stone ballast and it will make a floor for the teas, etc., at Canton.

“At Batavia you must if possible, get as much freight for Canton as will pay half or more of your charges; that is, if it will not detain you too long, as by this addition of freight it will exceedingly help the voyage. You must endeavor to be the first ship with ginseng, for be assured you will do better alone than you will if there are three or four ships at Canton at the same time with you....

“Captain Magee and Mr. Perkins are to have five per cent. commission for the sales of the present cargo and two and one-half per cent. on the cargo home, and also five per cent. on the profit made on goods that may be purchased at Batavia and sold at Canton, or in any other similar case that may arise on the voyage. They are to have one-half the passage money—the other half belongs to the ship. The privileges of Captain Magee is five per cent. of what the ship carries on cargo, exclusive of adventures. It is ordered that the ship’s books shall be open to the inspection of the mates and doctor of the ship, so that they may know the whole business, as in case of death or sickness it may be of good service in the voyage. The Philadelphia beer is put up so strong that it will not be approved of until it is made weaker; you had best try some of it first.

“You will be careful not to break any acts of trade while you are out on the voyage, to lay the ship and cargo liable to seizure, for my insurance will not make it good. Be very careful of the expense attending the voyage, and remember that a one dollar laid out while absent is two dollars out of the voyage. Pay particular attention to the quality of your goods, as your voyage very much depends on your attention to this. You are not to pay any moneys to the crew while absent from home unless in a case of real necessity, and then they must allow an advance for the money. Annexed to these orders you have a list of such a cargo for my own account as I at present think may do best for me, but you will add or diminish any article as the price may be.
