1177. KocK, G. Vergleichende Bodentemperaturmessungen. [Comparative soil-tem- 

 perature measurements.] Zeitschr. Landw. Versuchsw. Deutschosterreich 23:69-87. 1920. 

 — Comparative soil temperatures were taken at a depth of 30 cm. near the north, south, east, 

 and west walls of a trellis garden. The walls were 2 meters high and peach trees had been 

 trained against them. Temperatures were taken each day at 7 a.m., 12 m. and 6 p.m. for 1 

 year. Average daily and monthly temperatures, maxima, minima, etc., are given. Air 

 temperatures were also taken for comparison. Taking the whole year into consideration 

 the warmest situation for trellis-plants would be the south side of the wall, the east, north, 

 and west sides following in the order named. From a temperature standpoint, the north and 

 west situations are closely related as also are the east and south situations. Especially in 

 December, January, and February does the north side surpass the south and east sides in 

 temperature, and it is also considerably higher than the west side. In the other months, the 

 west side is somewhat higher in temperature than the north side and the south and east sides 

 surpass both. — John W. Roberts.
