_Bandaging Arms and Legs_--The reverse spiral is usually best for bandaging these, because of the conical shape. Practice alone can teach you to put this on smoothly, firmly, not too tightly, and at the same time quickly. A reverse bandage will not stay in place on the leg of the person walking around unless pinned in many places or stuck by sizing in the cloth (which has been wet), plaster, etc. Only a figure eight caught over the top of the calf, in each alternate loop, will do so. _The Figure Eight Bandage_--The figure eight is a modification of the spiral used in bandaging over joints in such a way as to permit some motion and at the same time keep the bandage firm and in place. The bandage is carried first below and then above the joint; then below and then above, the turns overlapping the usual two-thirds of the width of the bandage, leaving the joint free until the last. Then it may be covered with two or three circular turns of the bandage. This admits of considerable motion without disturbing the bandage to any extent. The National Red Cross and Girl Scout Instruction in First Aid [Illustration] By special arrangement with the National Red Cross, it is possible for a Girl Scout completing satisfactorily the requirements for the First Aid Proficiency Badge to secure with slight additional work the Red Cross certificate in First Aid. Or the course may be taken entirely under Red Cross auspices, though arranged by Scout officials, in which case the Scout may receive both the Proficiency Badge and the Red Cross certificate. The conditions of this co-operation between the Girl Scouts and the National Red Cross are as follows: Classes are to be organized with not less than four or more than twenty-five in a class. The best size is ten to fifteen. _Scouts must be at least sixteen years of age to be admitted to these classes._ The instructor must be a physician appointed by the Chairman of the First Aid Committee of the local Chapter of the Red Cross. He or she may be supplied upon request by the Chapter, or chosen by the class and the name submitted to the Chapter for appointment. The Red Cross class roll must be sent in to the local Chapter early in the course. A Secretary to handle the records should be chosen, and where the class is made up of Scouts, the officials should be preferably a Scout Captain or Scout Official. The examiner must be a physician appointed by the local Red Cross Chapter and is preferably some one other than the instructor, but this is not necessary. Like the instructor, the examiner may be supplied by the Chapter or chosen by the class. The Red Cross examination roll, which may be obtained from the Chapter, should be used in giving examinations and then returned to the Chapter, who will issue the certificates. Follow the directions on the roll carefully.
