The real trick was to have the lines cover the entire surface and then meet without leaving any empty spaces.
Having international fixed lines covered sounds nice and convenient and I'm sure it costs them almost nothing.
Several curved vertical and horizontal lines cover the circle to create an image of the globe.
Thick black smoke and a line of fire completely cover that end of the track.
The line of the Mongolian soldiers covered the whole horizon.
The line covered a space of several miles on the map.
The lines generally cover short distances between a few stations.
The line would have pretty nearly covered the same route as was eventually adopted by the B&M.
The other six lines cover towns further away, and normally have 30 or 60-minute headways.
The third line of approach is very broad and covers everything we call space applications.
