When you save a shapefile in ArcGIS it will not necessarily carry
projection information. The shapefile only has projection information
if it has a .prj file with it or, if you explicitly set the projection
using ArcToolbox (Data management / projections and transformations /
DEFINE projection), which creates the .prj file
