Mr. Eisenberg. Which is an interrupted ridge?

Mr. Dulles. I do not get the distinction.

Mr. Eisenberg. Is that an interrupted ridge you just described?

Mr. Latona. What we call an ending ridge.

Mr. Eisenberg. Off the record.

(Discussion off the record.)

Mr. Eisenberg. Back on the record. Mr. Latona, could you prepare a diagram which would show some of the characteristics, in broad outline, which we have been discussing, and have those labeled, and could you submit that diagram to us at a future date?

Mr. Latona. Yes; I could.

Mr. Eisenberg. We will append it to your testimony, so that your testimony may be more easily followed in the record—with the permission of the Chairman.

Representative Ford. It will be prepared and submitted and included in the record.
