To enable one to use the neck muscles also in addition to the shoulder straps a head strap is used. This is simply a double piece of ten ounce canvas two inches by twelve inches at whose ends are tied ropes which are attached to the pack. Browne has carried with this rig 100 pounds all day for several days at a time. Various styles of pack sacks are extant. The foreign sportsman has what he calls a rucksack which means a “back sack” and which is a triangular shaped affair usually of waterproofed materials which he hangs over his back by two straps passing up across the shoulders. The top is the puckered end of the sack and reaches up close to the neck, the flared out bottom hangs down to about the small of the back. It is sometimes fitted with pockets. It is very good for country road tours or for foreign sight-seeing trips where the items carried cover some such list as a noon day lunch, a raincoat, a change of underwear, photo films, notebook and guide book, but it is unsuitable for heavy weight work on the wilderness cruise. The haversack or knapsack slung by a strap from one shoulder is out of date and never measured up to the requirements for use in heavy packing. It is handy for lunches or as a ditty or emergency kit bag. The best pack sack was originated and put out by one Poirier of Duluth some twenty-five years ago and was originally really the whiteman’s improvement of the Indian tump line and pack cloth, ingeniously folded and tied so as to serve as a sack with suspension harness. As listed today by most outfitting firms it consists of a sack with shoulder straps and head suspension. It is a very desirable article from the point of view of the wilderness voyageur as he is enabled to ease up different sets of muscles while on the hike and [Illustration: DULUTH PACKSACK Illustrating head-band and single point suspension for shoulder straps.] [Illustration: Diagram for making packsack at home. Fold along the lines.] in handling a heavy pack the combined use of the neck and shoulder muscles are brought into play. This pack goes under the name of the Duluth, Poirier, Woodsman or Northwestern Pack and with slight modifications is listed under other names by various dealers in camp supplies. The genuine, however, consists of a simple flat bag of dimensions twenty-eight by thirty inches with adjustable shoulder and head straps. It has a large top flap with three long straps to hold it down thus enabling one to adjust it to a large or small pack. The following features are to be insisted upon--get the straps broad and soft and see to it that the connections are both sewed and riveted. The Poirier pack is much used on the Canadian border and is easily procurable or it can be made at home. All things considered and especially in view of the ignorance of the average man as to how to adjust his pack straps properly the Woodsmans or Poirier is the best.
