15th, 1908.
My dear Mrs.Summerhayes: Your good book and letter came yesterday p.m., for which accept my thanks.

My home is not in San Diego, but in Coronado, across the bay from San Diego.

That is the reason I did not get your letter sooner.
In one hour after I received your book, I had orders for nine of them.
All these books go to the official force of the Reclamation Service here who are Damming the Colorado for the Government Irrigation Project.

They are not Damming it as we formerly did, but with good solid masonry.

The Dam is 4800 feet long and 300 feet wide and 10 feet above high water.
In high water it will flow over the top of the Dam, but in low water the ditches or canals will take all the water out of the River, the approximate cost is three million.
