FIFTY-FIRST CONGRESS, 1889-1891. 1491 
The estimate does not include the buildings nor the bridge of the plan, it being 
assumed that the architect will inform you of the cost of these.. 
The estimate does not include a fence along the boundary of the entire park, but 
it does allow for enough fencing to inclose that portion of the park which is to be 
improved, and for numerous paddocks for the animals. 
The prices assumed are those usual for good work done by contract in this vicinity. 
Prices in Washington will probably be found a little lower. 
Approximate preliminary estimate.

The cost of suitably preparing public grounds under nearly all circumstances is 
much larger than the public is generally prepared to believe to be necessary, and it 
commonly occurs that the supposed excessive cost is attributed to a disposition to 
give them a highly artificial, ornamental character. For this reason we wish to
