Wilson Duke Football
| Wilson Duke Football |
California Bob reports:
This was a fun project. Passing a pile of discarded household items in my neighborhood, I spied a deflated football. I don't know anything about football really, but I recognized the Wilson Duke as a good quality ball, so I picked it up.
Was surprised to find a rebuild kit online for about $10, from a small biz out of Alabama who are obsessed with footballs -- new bladder, lacing, and lacing tool.
Then studied videos about how to re-lace. Fun project, no crawling on my hands and knees, wrenching my back or busting my fingers.
Inspecting it I see the ball is stamped with a big "K." Research indicates that this is an NFL "K" ball, used in NFL games for kicking plays (kickoffs, punts, extra points). The "15-4" on the right side indicates this is from week 15 of the season, K-ball #4 for that game. I can't, however, ascertain what season or what team. Maybe a sports shop can help me.
For now I have a nice football for my mantle.
PS: all Wilson Dukes still made by hand in Ada Ohio, tiny town near Lima, northwest of Columbus, and home to Ohio Northern University -- I knew a guy who went to law school there.
War
Stolen entire from Essays in Idleness by David Warren.
The task of war
One does well to examine the Song of Roland (the French, XIth century, chanson de geste) before jumping to conclusions about war. I particularly recommend Scott Moncrieff’s translation (1919), which had an introduction by G. K. Chesterton that has been anthologized elsewhere. He neither glorifies nor condemns war, and actually, neither did Roland in the “splendidly inconclusive conclusion.” War contains both good and evil characters and events, and is never finished in this world. Any final victory must wait patiently on God. So long as there are insane barbarians (the present regime in Iran offers an unambiguous example) they will have to be fought. It is inappropriate to “make peace” with such a vicious and deceitful enemy. And when there is fighting, there are casualties. The Lord — and Christ is not a milquetoast — does not require us to omit this task, and did not condemn it in His Bible. Those who fight for the right, deserve honour; those who insist on “peace, peace” regardless of circumstances are cowards who deserve contempt.
It is sad that there are people, even Catholics, who don’t understand this.
Probably should go read the Song of Roland (translation by Jesse Crosland), but I probably won't because it is 78 pages long.
Water

| An Engineering Student's Notes, Technical, Philosophical and Otherwise by John Richards |
JMSmith talks about clams and education and included this from the above book:
“I am beginning to think that water-craft, that is, human craft on the water, is much the same as it is in animals. It is absorbed in an insensible way throughout a term of years, or a lifetime, and is not a specific thing to be learned, like building houses or shoeing horses. A kind of second nature. Put a water-skilled man on a steamer, a ship, in a boat, on a raft, or a life buoy, it is all the same. He knows the traits and trends of the water, and how to keep on the surface of it. Geometry, dynamics, mechanics, or even a knowledge of Greek and Hebrew, will do him no more good than a heathen’s talisman, unless he has been trained to the water, on and in the water.” - John Richards, An Engineering Student’s Notes, Technical, Philosophical and Otherwise (San Francisco: Industrial Publishing, 1904), p. 155.
