are the poles, consisting of a hollow tube or. tubular shaft, which passes entire-ly through nuts on the shaft, by means of whichthe globe is confined on the collars F F. The shaft is thus fixed in position, and when the globe is inflated it may be revolved te represent the direct motion of the earth, the inclination of the axis or poles, and from this a correct idea may be conveyed of the orbital motion, the position of the earth in relation to the sun, the cause of heat and cold, the changes of the seasons, and vvarious other interesting phenomena in relation thereto'.

I do not confine myself to any particular manner of marking the globe to facilitate the study of geography. I am aware that globes now in use show seas and islands, continents, kingdoms, and cities.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In combination with an inflatable and collapsible geographical globe, the rigid poles B B, substantially as shown and described, for the purposes set forth.
