Clipping: Clipping trims features in one layer at the boundaries of features in another layer. This lets you work with layers that have a common spatial extent, making it easier to navigate a map.
To Clip a spatial attribute based within a layer you must select that attribute. I first created a new layer.
To Create a New Layer: (you could go to selection menu –Set Selectable Layers, then on the Tools toolbar click the icon to ‘Select Features.’ And click on the one you want, then right click on the layer Selection- create layer from selected features.) TADA
Then go to Arc Toolbox - Extract –Clip – Remember you are Clipping one layer based on another, the input is the layer that will be changed based on the output layer TADA
