5. The hide-out must be located where there are no curious or talkative neighbors. 6. The quarters must be sufficiently large to accommodate extra guests. Excessive cramping attracts attention. 7. The neighborhood should be well known to the owner and one in which some trusted friends reside. In this way any inquiries in the vicinity will immediately come to their attention. Meetings Elaborate security must surround all underground contacts, whether between just two people or groups. Here are a few points the underground has to remember: 1. Don’t use the same meeting place too frequently. It might excite suspicion. 2. If a meeting is held at a home, a member of the family (who, of course, is thoroughly reliable) should be there to answer the door in case an outsider knocks. He can handle the situation and also serve as a lookout. 3. If large numbers are involved, times of arrival and departure should be staggered. Everybody should not arrive or depart at the same time. 4. If the comrades don’t know each other, a predetermined means of identification (a code word, piece of clothing, etc.) should be used. 5. Bring no more documents (books, papers, etc.) than absolutely necessary. Avoid note-taking. Make effective use of memory. 6. Upon departure, a “rear-guard” comrade should thoroughly check for any incriminating items. Have any papers been left on the floor? Is there a telephone number scratched on the wall? Has someone forgotten his coat, which might contain Party data? In one instance six weeks allegedly were spent in bringing twenty people to a national underground conference. If two comrades don’t know each other, advance arrangements must be made, usually by notes, to effect identification for a meeting. Here is one example. The note read: On Friday, April 6, 8 P.M. at NE corner, Oak and 9th Sts.—my courier will be standing with a _Field and Stream_ magazine. Bill’s courier will approach her and ask, “Mrs. Polk, what time is it?” She will reply, “I’m sorry, my watch is stopped.” Note the use of a magazine and code words for identification. Just in case the first contact didn’t work out, there were alternative instructions. The note continued: In case no one shows, she will be on the SW corner, Walnut and 10th, same magazine, Friday, 13, 8 P.M., same question and answer. She will wait around only ten minutes each time. Noncommunists probably will find it difficult to understand the reckless abandon, personal risk, and sheer physical endurance displayed by communists to conceal their underground activities. Here are a few of the tactics employed by communists to determine if they are being followed: _Driving cars_: 1. Driving alternately at high and low rates of speed. 2. Entering a heavily traveled intersection on a yellow light, hoping to lose any follower or cause an accident. 3. Turning corners at high rates of speed and stopping abruptly.
