In making these cuts on ^, as wellas the corresponding cuts on (7, and anyothers which go lengthwise of the grain, becareful not to hold the saw quite horizontally,or with the tip inclining downward, as incross-cutting, but with the handle downwardas in ripping, as in Fig. 50. Otherwise the. teeth will stick too firmly in the wood,and the saw will jump, or chatter. Inmaking cross-cuts, as the two short cuts inC, this precaution is not necessary. 116 Manual Training.
