I spent a little time at Heritage Square Museum yesterday.
The docent brought up an interesting point. The Perry Mansion, (the white home on the left) built in 1876, cost considerably more to build than the Hale House, (on the right) built in 1887.
And contributing factors to that change in cost, were that in the intervening span of 11 years, huge progress was made in the ability to transport raw materials from one point to another cross country; and equally huge progress was made in the ability to mass-produce materials.
We often talk about the enormous, mind boggling changes in technology and business that have occured in the last ten years. I'm thinking the people living in the 1876 to 1887 period might have felt the same way.
