But as neither conclusion could have been correct, as no such terrace has been found in any part of this region, and a walk around the summit would have thwarted the very design they had in view in building the mound, what was it Garcilasso's informants saw? C. C. Jones says "a terrace," but it is scarcely possible that any terrace at the end or side of a southern mound, forming an apron-like extension (which is the only form found there), could have been so described as to convey the idea of a roadway, as the mode of estimating the width shows clearly was intended. [Illustration: FIG. 39.--Large mound of Etowah group, Bartow County, Georgia.] The broad way winding around and up the side of the Etowah mound (Fig. 39) appears to answer the description better than any other in Georgia. It is a large mound, high, and one that would doubtless attract the attention of the Spanish soldiers; its dimensions indicate that the tribe by which it was built was strong in numbers and might easily send forth five hundred warriors to greet the Spaniards. The locality is also within the limits of De Soto's route as given by the best authorities; and lastly, there is no other mound within the possible limits of his route which will in any respect answer the description. As Garcillasso must have learned of this mound from his informants, and has described it according to the impression conveyed to his mind, we are justified in accepting it as a statement of fact. I am, therefore, satisfied that the work alluded to is none other than the Etowah mound near Cartersville, Georgia, and that here we can point to the spot where the unfortunate Adelantado rested his weary limbs and where the embassadors of the noted cacique of Cutifachiqui delivered their final message. [Illustration: FIG. 40.--Vertical section, small mound, same group.] Recently the smallest of the three large mounds of this group was opened and carefully explored by Mr. Rogan, one of the Bureau assistants. As the result will be of much interest to archæologists aside from the question now under discussion, although belonging to the southern type of burial mounds not discussed in this paper, I will venture to give a description of its construction and contents as a means of comparison and as also bearing somewhat on the immediate question under discussion. This mound is the one marked _c_ in Jones's plate;[72] also _c_ in Colonel Whittlesey's figure 2.[73] A vertical section of it is given in Fig. 40. The measurements, as ascertained by Mr. Rogan, are as follows: Average diameter at the base, 120 feet; diameter of the level top, 60 feet; height above the original surface of the ground, 16 feet. The form is more nearly that of a truncated cone than represented in the figures alluded to.
