The undercutting process re-quires at least two passes by the tractor-mounted cutter/shaker. The Contractor will not begin lifting trees from any under-cut area until authorized by the COR or Government inspector. 210 Boxing of Seedlings Each box or tub will contain three layers of seedlings. Each layer of trees will be separated by a double layer of burlap covering the roots. Starting at bottom of container, the burlap will be laid in an "S" pattern over each layer of trees. The remainder of the burlap strip will be used to completely cover the top of the seedlings and then tucked in around the edges. 220 Field Handling of Seedlings Pullers will properly lift and handle tree seedlings so as to avoid injury or un-necessary exposure to harmful elements. 1. Seedlings will be lifted from the seedbed by grasping two handfuls of seedlings at the soil line and lift-ing with a steady pull, not jerking, them free from the soil. Extreme care must be taken to avoid bending or kinking tree stems. 2. After shaking seedlings to remove all loose soil, the stock shall be immediately placed in the tree box. Seedlings must not be exposed to the open air for more than 20 sec-onds from the time they are pulled from the ground until they are placed in a box and covered with burlap. 3....
