As there is nothingto prevent the roots of the seedlings from interweaving, it is necessarvto cut crosswise and lengthwise between the trees in order to separatethem. This destroys the roots of each tree somewhat and loosensthe soil allowing the roots to dry out so that a few trees usually making partitions of pieces of pasteboard fitted together as in eggcartons and dipped in melted paraffine, a flat may be partitioned sothat the root system of each tree has an equal chance. Figure (3)shows a partitioned flat (on the right) and another flat containingcylinders made of single pieces of pasteboard fastened with foldedpieces of tin and dipped in paraffine. The crude paraffine can be boughtat 10 cents per pound. Cans from which both ends have beenremoved may be used instead of pasteboard cylinders. 12. FIG. 3. PARTITIONED FLATS, PASTEBOARD CARTONS AND CYLINDERS (3). Planting Out. Directions for setting out trees have beengiven in two State bulletins(*). The important points are as follows: (a) Set in deep soil if possible. (b) Have the soil thoroughly prepared beforehand. In pre-paring for county road planting have three or four furrows turned inthe fall and wait until January or February to set the trees. (c) Dig the hole larger than necessary to contain the roots;till in with pulverized surface soil below and around the roots. Insetting street trees a foot of sand, gravel or poor soil on top will tendto direct the surface roots downward and thus prevent crackingcement walks. (d) Tramp the soil firmly while filling in. Water thoroughlyafterward so as to pack the soil around the roots. (e) Trees that have been held for some time in tin cans willdevelop faster if the can is slit down the sides with tin shears, or ifthe can is entirelv removed. (*
