72 AN AUSTRALIAN STUDY OF AMERICAN FORESTRY. 
One is the “threading board,” which consists of two light planks hinged 
together, and closing upon each other, thus holding in place the seedlings 
which are set out evenly along it, their roots outwards. This board is placed 
in the trench, and the soil pressed round, after which it is opened and lifted, 
leaving the seedlings in situ. ;

(a.) THE OLSEN PACKING BOX. 
{b.) THE OLSEN SHIPPING ROLL COMPOSED OF HESSIAN, PAPER, AND WOOD WOOL. 
A considerable saving in materials, labour, and weight is effected. 
The paper makes the roll wind proof. 
It has been constructed with minute care, after close experimentation, 
and is so worked out that the time required for one man to plant a board, is 
exactly the time required by his fellow-worker to put the seedlings in another 
one. : 
It is 84 ft. long, holding seventy-five plants in seventy-five notches, 
placed 14 in. along its inner edge. It is fitted with a self-clamping hinge. 
I secured a drawing of it, a copy of which is attached. 
The other invention is the “threading table,” which is a portable bench 
with a trap slide in the centre, down which the filled threading board is 
pushed to a shelf below opening on to the back of the table. Above it is a 
rack for holding the “seedling packet.” It is walled and roofed in with 
canvas to shelter the threader, and to prevent the seedlings being blown from 
the board during threading operations. 
At this table stands the threader, who sets the seedlings in the board 
ready for planting.
