A Tennessee correspondent, after informing us that we are indebted to an article on this subject by Hoe & Co., in the second nnmber of our present volume, for many subscribers in his locality, proceeds to give the following practical information: " As well as the number of teeth being proportioned to the hardness of the timber to be sawed, their number should also be proportioned to the power used. Each tooth of a saw can only cut advantageously a certain distancc forward in passing through thc log, which distance depends on the hardness of the wood; but if a saw has a great many teeth, and is driven by a weak power, each tooth will not cut so far forward as it should do, and there is a loss of power. If the power is great, and the number of teeth few, then each tooth will have to cut too far forward."
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
