Survey of Northeast Greenland. 239 
The above-mentioned unreliable sight from XV to Haystack 
gives in the case of Haystack ф = 75°43'03” and I = 19°25'17”. As 
was to be expected, there is a very considerable difference between 
the two values of the latitudes, whereas the longitudes are very | 
nearly the same. 
In the map of the Germaniaexpedition Payer makes use of three 
different signatures for his observation stations. The first sort he 
calls “Astron. trig. Standorte’, and hereby he indicates, as far as I can 
see, only the triangulation station determined by the geodetists BORGEN 
and CopELAND in their attempt of gradimetry. These stations are 
determined by a complete measurement in thirty-six sets. The other 
sort he calls “Trigonometrische Fixpunkte”, the third sort “Graphische 
Punkte”. 
Оп Payer’s map Haystack is designated as “Trigonometrische 
Fixpunkt”. 
Beyond the map Payer has, unfortunately, published nothing 
about his observations. By a lucky chance Koldewey, however, 
published the bearings of three of PayEr’s sights at Haystack. 
During the sledge trip in 1870 to Germania Land Koldewey 
determined the co-ordinates of Haystack at @ — 75°44'.5, I = 19°10’). 
As in particular the longitude differs considerably from the one indi- 
cated on PayEr’s map, Koldewey takes occasion to remark in a foot- 
note: “Die Lange von Haystack ist auf der Payer’schen Karte...... 
zu 19°23’ angegeben. Es sind fir die Construction folgende Winkel- 
messungen benutzt worden. 
Z Tellplatte—Kap Bremen—Haystack ...... ТЭН. 
Z. Tellplatte—Muschelberg—Haystack ...... 130°33’ 
Z Kl. Pendulum—Keferstein Berg—Haystack 77°14’. 
Of the three angles given Tellplatte— Muschelberg— Haystack 
must necessarily be encumbered with a very serious error (130°33’ 
is possibly a printers’ error for 103°33’). This direction must thus 
be condemned, and the co-ordinates of Haystack must consequently 
be computed from Keferstein Berg and Kap Bremen. But before this 
a computation must be made of the triangle Keferstein Berg—Klein 
Pendulum—Kap Bremen. This triangle looks as follows: 
Z Kap Bremen—Keferstein Berg—Kl. Pendulum. . 109°28’15” 
Z Keferstein Berg—Kl. Pendulum—Kap Bremen.. 55754754” 
Z Kl. Pendulum—Kap Bremen —Keferstein Berg.. 14°36'51” 
log (Kap Bremen—Keferstein Berg) — 4.720858.
