Troubleshooting Mathematic's Help

In an old, old book by Bill Davis, Horacio Porta, & Jerry Uhl I saw an 
example of how to draw a vector, e.g.,

<< Graphics`Arrow`

X = {3, 4};
Show[Arrow[X, Tail -> {0, 0}, Blue],
Axes -> True,
PlotRange -> All,
AxesLabel -> {"x", "y"},
AxesOrigin -> {0, 0}];

Not being that familiar with Mathematica, where would be the best place to 
start to debug this?  Error message indicates it could be a problem with 
Tail and/or with Arrow, looking at master index Arrow looks OK, unless it 
needs to be embedded within the Graphics command?  Thanks in advance,
