48 L. F. Ward — Famous Fossil Cycad. 



finally wrote to .Dr. Emil Tietze, the distinguished Director of 

 the k.k. geologische Reichsanstalt, to learn if possible whether 

 this district had been surveyed and if so where I could find the 

 report, maps, etc., He replied promptly and informed me that 

 he had himself made this survey and published the results in 

 1887.* 



In my letter to Director Tietze, dated November 12, 1903, I 

 said: 



"I note that most of the region about Cracow is mapped as 

 Tertiary. It does not seem probable that the specimen could 

 have come from the Tertiary, as all similar trunks, from what- 

 ever part of the world, have been found in much older strata, 

 ranging from the Middle Jurassic to the Lower Cretaceous. 

 The specimens most closely related to it in America occur in 

 the Lower Cretaceous of the Black Hills, South Dakota." 



In his reply of December 10, he says : 



" The salt formation of Wieliczka is certainly Tertiary and 

 Miocene. The Cycadeoidea Reichenbachiana surely does not 

 come from this salt formation, the flora of which is in fact 

 known from the works of Unger and Stur. But at Lednice 

 the beds of the Miocene salt formation do not occur. There 

 are developed partly Oligocene, partly Lower Cretaceous 

 deposits. Probably, therefore, the specimen in question came 

 from the Lower Cretaceous of Lednice. Still, I must admit 

 that thus far the presence of fossil plants was not known here, 

 and also that in the general region about Wieliczka such 

 remains have heretofore scarcely been found. This is of course 

 no reason for doubting their presence at this locality." 



A glance at the fourth sheet of Dr. Tietze's Map (Jahrb. 

 1887, pi. xix), shows that beds colored for iNeocomian occur at 

 Lednice and throughout that general region, and it seems there- 

 fore next to certain that it was from these beds that the speci- 

 men was primarily derived.
