Thank you Paul.
This happens in many cities and is completely misguided. Good studies show that trees in a neighborhood reduce crime and improve the quality of life. By the way, I grew up in the glorious forests of Baltimore. Really! Thank you!

Excellent! It’s rewarding to have pictures of the same tree at different times. I especially like the base of the tree in these photos.

I think it likely that there were many thousands of sticks used by hominins before this one, but wood decays and disappears. What makes this a cool stick is that it somehow remained.

My advice would be to start her on violin and then let her choose. Violins for kids are more affordable, and it is easy to find teachers.

A story about the amazing viola and two of its most notable performers. Some thoughts after watching Rebecca Albers perform a new work for viola and orchestra.

Thank you. I haven’t seen the word bindlestiff in some time, but it is apropos.

Great story, Erik, but “hopping”? Really? I once had a king cobra under my desk in Borneo, but it certainly was not hopping.

Technology is taking away our connections to each other and to the natural (i.e. real) world. @rebeccasolnit.bsky.social offers an insightful look into what is wrong and how to fix it. I hope everyone reads this.

Excellent. Many of us Vitamin M enthusiasts develop a favorite for which there is no substitute. I hope you find another good source.

My college, SUNY-ESF, has had a sugarbush in upstate New York for many years. It's the best Vitamin M I've ever had.

I just got a delivery that has taken more than two weeks to arrive. I suppose the weather is to blame. The order was for what in my family is known as Vitamin M and for which there is no substitute. The package arrived just in time to prevent serious consequences. Now for some vegan pancakes.

Here is an ancient bur oak next to a young loblolly pine, on left in midwinter, and on right in summer. Today is a deeply cold winter day but the oak and pine are no longer dormant. A cold period has eliminated the inhibitors that prevent growth. The trees are ready to grow when it is warm enough.

Many of us are about to be visited by complex weather, possibly including ice storm. Ice can do major damage to trees, even kill them, but an ice-covered tree is hazardous to you. These trees should not be touched. Here are some simple suggestions for managing ice-covered trees.
