large stakes driven eight to ten inches into the ground. The observation 

 was therefore deemed entirely satisfactory. At the next station on the 

 next night an observation vsras made the same interval before elongation, 

 and the difference betvsreen the azimuth of the star and that of elongation 

 agreed w^ithin a quarter of a minute virith that at Station 129.

 ris observed at 11 o'clock p.m.
