Mr. MAMANTOV. No; we got to Seminole--one more place I went from there. No; two more places--I went from Seminole to Snyder, Tex., and from Snyder, Tex., I went for 3 weeks to Forest, Miss., and at that time I quit the company and got my job with Sun Oil Co. here in Dallas. Mr. JENNER. With Sun? Mr. MAMANTOV. Right; and purchased our home at 6911 East Mockingbird in October, the 1st of October 1955. Mr. JENNER. Now, what is your facility in the command of the Russian language, with particular reference to--did you or have you done any teaching of the language? Mr. MAMANTOV. Yes; I am teaching since 1960 here in the Dallas area. I taught scientific research to some men, of a research personnel in 1960-1961. And, I taught in the Austin College in Sherman from--it was the fall of, yes, it was fall of 1961 and 1962. No--1962 and 1963. Now, I am teaching at SMU or Dallas College, to be specific, of SMU. Mr. JENNER. Have you done any interpreting or translating? Mr. MAMANTOV. Yes, sir; for the American Geophysical Union, quite extensively in 1959, 1960, and 1961, and I think--yes--1961 I finished. Mr. JENNER. And have you also done any interpreting or translating for any law enforcement agencies? Mr. MAMANTOV. Here in the States? Mr. JENNER. Yes. Mr. MAMANTOV. Let me think a little--no, I don't remember. I have translated minor papers, you see, like Soviet Union's marriage certificates and birth certificates for our local courts connected with divorces, and I might be of a help to a group of Latvians, people here in town, when they received their citizenship, so much, but this is the first time for the police department. Mr. JENNER. All right. I'll get to that. Have you ever been called upon by either any agency of the Government of the United States or of the State of Texas or the City of Dallas to do any interpreting or translating? Mr. MAMANTOV. Yes, I was called by the police force for the City of Dallas around 5 o'clock, November 22. Mr. JENNER. What year? Mr. MAMANTOV. Of 1955, on 2 or 3 minutes' notice. Mr. JENNER. It was 1955 or 1963? Mr. MAMANTOV. Excuse me, 1963. Mr. JENNER. I got from what you have said, then, you had no prior notice? Mr. MAMANTOV. No; sir. Mr. JENNER. You were called by some official of the city police department? Mr. MAMANTOV. Yes; I was called by Lt. Lumpkin. I think he's Lieutenant--they call him Chief. Mr. JENNER. And you repaired then to the Dallas City Police Station? Mr. MAMANTOV. Excuse me, I was called by somebody else, a couple of minutes ahead of Lumpkin--is it important? Mr. JENNER. I don't know--you might state what it is. Mr. MAMANTOV. All right. I was called by Mr. Jack Chrichton, C-h-r-i-c-h-t-o-n (spelling)--I don't know how to spell his name right now, but I guess it is that, but I can find out in a day or two. Mr. JENNER. And who is he?
