good skins within five per cent of perfection than to mount one poor one not nearly so well. Let me advise the directors of all scientific museums, institutions of learning, and patrons of natural history generally, when appealed to by an enthusiastic collector for funds with which to go abroad and collect an untold amount of priceless specimens, in every case withhold your aid until the would-be collector demonstrates conclusively that he has learned how to collect. If he has not wit enough and grit enough to acquire ability, and then prove property, he is not fit to send anywhere, save back to the bosom of his family.

These are the qualities which are required to make a first-class collector: He must have a fair general knowledge of zoology, especially the vertebrates. He must be a good shot, a successful hunter, and capable of great physical endurance. Then he must be a neat and skilful operator with the knife, and conscientious in the details of his work, down to the smallest particulars, for without this quality his specimens will always be faulty and disappointing. In addition to all these requirements he must be a man of tireless energy, incapable of going to bed so long as there are birds to be skinned, and who, whenever a doubt arises in his mind in regard to the necessity of more work on a specimen will always give the specimen the benefit of the doubt.

I strongly advise every one who becomes a collector to learn to sketch from nature. No matter whether you have any artistic ability or not, if you are determined about it, you can learn to make pencil sketches of rare specimens in the field, and of native houses, costumes, weapons, etc., and remarkable natural objects of all kinds, which, even though crude and inartistic in finish, may be of permanent value to the scientific world. The camera and dry plate are of great value, but commend me to the pencil and sketch-book that "sticketh closer than a brother," and that never fail you on account of weather, weight, or accidents. Therefore I say, sketch; sketch poorly if you cannot sketch well, but above all, sketch.

The moment you make up your mind to go on a collecting trip, even if be only into the next county, read everything you can get hold of which will tell you aught about the natural history of the country you are to visit. Ask what has been written, search library catalogues for titles of books, then get all you can, and read all you get. Only the churl will refuse to lend you a book you cannot afford to buy. Read all about the physical geography, geology, climate, inhabitants, fauna and flora, for all these will have a direct bearing on your work. If you are going to unexplored territory, about which nothing has been written, then "read up" on the adjacent countries, for even that will be very useful information.

Guides and Companions.—No matter where you go, you will be obliged to have one or more companions, who know the country, to act as guides and general assistants. It may be that you can find a single person combining the necessary qualities of a guide and interpreter with those of a boatman, a teamster, or porter. The expense of such assistants must be counted upon from the very first. It may be stated as a general rule that in the tropics the services of natives can be had cheaply; while those of Europeans are generally dear in comparison with what they do.

Clothing and Food.—These subjects I propose to leave entirely alone. They make excellent "padding" for a work of this kind when there is a lack of really useful information with which to fill up; but every man feeds and clothes himself according to the dictates of his temperament, his purse, or his own sweet will. Whether his way is the best or the worst, he will still have food and clothes more or less suitable to his needs, and time spent in advising him what to wear and to eat is time wasted. These questions are generally controlled by the locality and circumstances.

Preservation of Health.—There are certain hygienic principles which apply all the world over, and since their observance becomes in the tropics a question of life and death, I will record them. Their observance has preserved my health intact in unwholesome jungles in a way that I consider nothing short of wonderful.

Never sleep on the ground in the wet portions of the tropics when possible to avoid it, but keep above the poisonous miasmatic vapors that lie close to the earth.

Boil water before drinking it, if it is thought to be bad, and avoid stagnant water at all times.

Drink no spirits whatever except when really sick or debilitated, nor wine, nor other alcoholic beverages. Avoid brandy, whiskey, and rum as you would the plague.

Eat no unripe fruit, and with moderation of even ripe fruits, excepting bananas, which are harmless and most excellent food.

Avoid eating large quantities of meat, but give the preference to rice, and farinaceous foods generally.

Wear light flannel shirts, and at all hazards keep the head and nape of the neck well shielded from the sun. Pith helmets are best.

After getting wet, do not sit down in the hot sun with your wet clothes on, but if you must remain in the sun, keep moving.

By means of rubber clothing, or "ponchos," keep from getting wet whenever you can.

On coming into camp with wet garments, do not sit down in them to rest, but change immediately to dry clothing and footgear. The strict observance of this rule will save many an attack of fever.

Medicines.—Every traveller or collector who goes beyond the ready reach of doctors (and for that matter also every family living in the country) should have a small box filled with certain medicines and simple appliances as a resort in all cases of emergency. Very often a deal of mischief can be prevented by having the proper remedy at hand and ready for immediate application. Who has not seen great suffering endured for the lack of a simple remedy costing only a few cents? No matter where I go in the field, or how much luggage I am impeded with, I always carry with me a small, square, japanned tin box (10 inches long, 7 inches wide, and 4 inches deep) which contains the following:
