The compression specimens and beams v/ere left for abouttT/o v;eel:s in the position in -aiich they v:ere made on the floorof the mixing laboratory, when they were piled one on top ofanother with v/ooden blocks betv:een them. They v/ere spririlcledmore or less each day T:ith4 a hose to prevent drying- out, butthe are that the use of more water would have beenbetter because water was so quickly absorbed by the specimen. The mixin£^ laboratory in which the specimens were storedwas heated by steain pipes. The temperature varied from 73°p to44°P except that once, on January 15, 1912, the record showsthat the temperature dropped to 34°F. Temperature was recordedat 7 and 5 each day, and it is probable that the var-iation was somewhat greater than £;iven above. The generalrange was from 30°F to 70°F. The actual daily variation isshown in Fig. 4, page .31. Specimens 205Z, 2065 and 2073 were hauled to the testiriglaboratory some time before they
