THE TWO METEOROLOGISTS
N 25 ON THE WAY TO OSLO
I am going to cite some figures from this book which give a clear reply to the question, Which time of the year is the best for flying to the Pole?

| „ September | 0 |
| „ October | 4 |
| „ November | 11 |
| „ December | 15 |

It happens, of course, that in the summer time the sun breaks through the sky at some time of the day, but even that is not very often.
