In the first they are lapped over each other as [fig. 15]. This method gives a strong connection, but prevents the putlogs being laid evenly.

The second way provides that the ledgers shall lap horizontally side by side. This allows of evenness of line for the putlogs, but is not so strong ([fig. 16]).
In both of these methods the lap should cover two standards, and not as shown in [fig. 17].
The third manner of connection ([fig. 18]) is the best. The ledgers butt end to end. Underneath, a short pole is placed crossing two standards. The tying at the standard embraces the double ledger. A band tie is run round the supporting pole and the ends of the ledgers where they butt.
Great strength is obtained in this way and the putlogs can be evenly laid.
Additional ledgers are fixed as the work proceeds.
