密歇根大学最初的校园几乎是一个边长约半英里的完美正方形。一条街道大小的步道，恰当地称为“迪亚格”，斜穿过这个广场，连接其东南角和西北角。 1904 年，一座新的工程大楼要么开工，要么竣工（我不记得是哪一栋），用于容纳教室。多年后，当街对面的扩建校园内建造了另一栋工程大楼时，旧建筑被称为西发动机，以区别于新的东发动机。老西部引擎是（或者现在可能是）一座四层楼的 L 形建筑，位于原校园的东南角。它建有一个拱门，横跨 L 形顶点处的 Diag。如果你在建筑物内，你可以走过工程拱门从 L 形的一条腿到达另一条腿，当你从东南角进入校园时，你可以从它下面走过。拱门的砖石墙上贴着一块我经常路过的牌匾。上面引用了霍勒斯·格里利（Horace Greeley，1811-1872）的名言，当时我并不知道他是《纽约论坛报》的创始人、编辑和出版商。简单地说，年轻人，当理论与实践不一致时，运用你的马感。这个建议似乎值得用感叹号而不是句号，但我不记得它是否有感叹号。
The original campus of the University of Michigan was nearly a perfect square about a half-mile along a side. A street-sized walk, appropriately called the Diag, runs diagonally across this square, connecting its southeast and northwest corners. In 1904 a new engineering building was either started or finished (I do not remember which) to house classrooms. When another engineering building was built on the expanded campus across the street from it many years later, the old building came to be known as West Engine, to distinguish it from the new East Engine. Old West Engine is (or maybe by now, was) a four-story, L-shaped structure that stood at the southeast corner of the original campus. It was built with an arch in it to straddle the Diag at the apex of the L. You walked over the Engineering Arch to get from one leg of the L to the other if you were inside the building, and you walked under it when you entered the campus from the southeast corner. Affixed to the masonry wall of the arch was a plaque I often noted in passing. It bore a quote attributed to Horace Greeley (1811-1872), who I did not know at the time was the founder, editor, and publisher of the New York Tribune. It said, simply, Young man, when theory and practice differ, use your horse sense. The suggestion seems worthy of an exclamation point instead of a period, but I do not remember if it had one.
