Since it was built in 1895, it has been necessaiy to enlarge it several times to meet the constant ly increasing demand. The interior is elegant, cheerful and tasteful. No modern convenience is lacking. There are bath rooms, electric lights, steam heat and opeD fireplaces. There is a call bell in every room, and all beds are furnished with best hair mattresses. An orchestra furnishes fine conceits daily, and also provides foi dancing. The cuisine is unsurpassed. The waitresses are all white girls from the North. Rooms for billiards and other games are provided in the hotel. A. I. CREAMER, Manager. W4 The Harvard, PINEHURST, N. C.

MOKELESS powder is a subject every sportsman can and loves to discuss, but not from the tech nical side, and in view of the lack of knowledge in this particular, a few facts in relation to its making and testing cannot fail to be of more than passing interest. Such an article The Outlook has been forainate in securing from E. A. Whistler Everitt, Du Ponts Uallistic engineer. F. H. ABBOTT, Manager All smokeless shotgun powders at present in use are divided generally into two classes, one being known as a "bulk" powder, under which head is manufac tured Du Pont, "E. C.,' "Schultz' and Hazard, and the other as a "dense" pow der, "Infallible" being the only dense shotgun powder of Du Pont manufac ture, in fact it is the only dense powder made in America. "Bulk" powders are manufactured in such a manner that they can be loaded with the same measure used for "black" powder, whereas "dense" powders are manufactured so that they require a very much smaller charge than the "bulk" powders. All cartridges loaded with a "dense" are loaded by weight instead of with the ordinary "black" powder meas ure which formerly was known as "Dix on's Standard 3 Dram Measure." Each class of powder has its friends, who will argue that one class ha supe rior qualities over the other, and the dis cussion of this question is best left to the individuals who think their particular choice is the best. The manufacture of these two differ ent classes of powders is distinctly dif ferent, although the results obtained after the powders have been made and loaded are practically the same. In other words : Corresponding charges of "dense" and "bulk" powders will give about the same results as regards veloc ity when fired in a shotgun. ID may be known to the average con sumer or dealer that the basis of these powders is generally Guncottorj, or Gun cotton and Nitroglycerin. "Bulk" pow ders are made from Guncotton combined with other ingredients,, whereas ' 'dense" powder is manufactured principally of Guncotton, Nitroglycerin and other sub stances. The majority of shooters may think that because a powder contains nitro glycerin, it is similar in effect to dyna mite, but this is a great mistake, as at the present day, Nitroglycerin and Gun cotton can be handled as safely as any of the other ingredients in the powder. After these substances have been man ufactured into powder they are absolute ly safe if handled with ordinary care. In the manufacture of either a "bulk" or "dense" powder, each individual in gredient that goes into the explosive is tested thoroughly and must fulfill certain requirements before it is allowed to be used. The following will give a very general idea of the methods pursued in making n standard "bulk" powder: The cotton used in the manufacture of Smokeless Powder before it is rendered in anyway explosive, is in the ordinary form of cotton that every one knows. The "raw" cotton is nitrated by the aid of Nitric and Sulphuric acids, and thus becomes nitrated cotton, or guncotton. After the nitrating "process it is boiled and re-boiled and then washed in cold water until all the acid is freed from the cotton and it has attained a degree of purification whicli satisfies the approved chemical tests. The guncotton is then put in special machines and ground very tiue, after which it is washed and re washed for any further trace of acid. During these washings, repeated tests are made to insure the absolute elimina tion of every trace of acid from the cot ton. It is then set aside in large recepta cles to be used later in the manufacture of the powder. In the actual manufacture of a "lot" of powder, of course, the formula used is one that has been determined by many years of experience and by a great many experiments, and when the operation is started, certain quantities of each mate rial are weighed out and mixed by a spe cial machinery into what will ultimately become the finished powder. After the powder is finally made, it is put aside and other batches are made up along the same lines. Whan a number of these lots have been manufactured, certain quantities are taken from each lot and blended together in a spe cial building by special apparatus that insurts a thorough and perfect blend of the entire mass. The next operation is to get the proper size grain. This is done, by repeated bolting with sieves that will give the re quired granulation to the final product. After this process the powder is taken to the Proof House where it is to be test ed. The tests consist of loading up a num ber of cartridges containing 3 drams and 3 drains of powder. These loads are test ed in order to see that the powder has the proper velocity and that the breech pressure is well within the safety limit. The velocity test is determined by special chronographs which time the flight of the shot from one point to another, and by this means the average speed of the shot can be determined very accurately. These instruments are sim ilar to those in use at all of our Govern ment testing stations and to those used in European countries. They are so finely adjusted that they can be made to read to the 1-40,000 ths. part of a sec ond. In the breech pressure test, a small hole is bored into the cartridge just above the powder charge, and the car tridge is fired in a gun which has a pis ton acting directly above the hole in the shell. When the cartridge is fired the gas f romthe powder acts on the base of this piston, which in turn acts on a small lead cylinderheld in place above the pis- I
