It has been suggested that baling might have a ten-dency to close up the chips and render penetration bythe cooking liquor more difficult than with ordinarychips and the criticism has also been offered that thechips might be considerably broken up in the balingprocess. Chips from some of the bales made have beenexamined but in no case could a tendency toward clos-ing up or breaking up be discovered. There are many advantages to be derived from theuse of dry baled chips. Purchasing by weight insteadof volume and buying chips of a known moisture con-tent will ensure the buyer of getting a known amountof wood instead of a very variable amount as where.

Freight charges on alot of more or less useless material such as bark andsawdust which at best can only be used as fuel will beavoided. There will be very little danger of dry rot,as is the case with wood stored in yards, for eventhough the chips have to be stored the low moisturecontent will greatly reduce the danger of fungus infec-tion. Several advantages are claimed for the use of drycliips in the manufacturing process. There is a de-crease in volume when chips are dried and this allowsa greater amount of chips to be charged into thedigester than with wet chips resulting in an increasedyield of pulp per digester.
