in place, and in addition the number may be pasted on the partition wall 

 of the pigeonhole either above or below. 



2. A cabinet similar to the above with the drawings enclosed in cartons 

 with metal tops, the number of the drawing or drawings being posted on 

 the metal caps. This method is especially commendable because it ensures 

 absolute cleanliness of the records. 



3. A large case or cabinet having a number of shallow drawers into 

 which the record may be filed flat. The chief advantage of this method is 

 that the records are easily handled, being always unrolled. Unless, however, 

 a very large case or several cases are provided, it is very difficult to segregate 

 the records in such a manner as to facilitate the finding of a particular 

 record. The number of each record is usually printed in prominent letters 

 on the lower right-hand corner, and a list of the records in each drawer 

 may be posted on the front of the drawer. For cross reference purposes 

 each drawer may also be given a letter or a number. This method of filing 

 does not protect the topmost record from becoming very dirty unless a 

 sheet of paper or a cloth the size of the inside of the drawer is kept constantly 

 on top therein. 



4. A cabinet similar to the above is sometimes used except that the 

 drawers are deeper and the records are rolled and placed in the drawers. 

 This is the least desirable form of filing because of the difficulty of finding 

 any particular record desired. 



5. In park offices where the engineering records are not very numerous, 

 an upright cabinet with a lid opening outward so that it can serve as a 

 table is sometimes used. Inside are a number of clamps into which the 

 records are fastened and suspended vertically in the cabinet. Each record 

 bears a number, and an index of the records may be posted on the inside 

 of the lid. 



6. Another type of filing cabinet is sometimes used which from the 

 outside has the appearance of a large drawer cabinet turned on end. Each 

 one of the upright compartments is suspended on a roller bearing appliance 

 which permits ease of movement outward and inward. On either side of 

 each compartment is arranged a series of V-shaped receptacles into which 

 the rolled records are placed. Each record bears a tag showing its number 

 and on the outside of each compartment is an index of all the records in 

 that particular compartment. 



These various types of filing cabinets may be of metal or wood. While 

 the steel cabinets would not preserve the records during an intense fire, 

 they do ensure a measure of protection against fire not possessed by wood. 

 In connection with any of the different methods of filing this type of record, 

 a cross reference card index system is absolutely essential to keeping track 

 of the records.
