I cannot get this code to show the solutions to the equation, only the vector plot.  Whats wrong?  It came from Schum's Outline, Mathematica 2n ed, solved problem 11.3 on page 272-3.  The only changes I made was using v1 for vf and s1 for solutions.

v1 = VectorPlot[{1, x^2 + y}, {x, 0, 1}, {y, 0, 12}, 
   Axes -> Automatic, VectorScale -> Tiny];

s1 = Table[
   DSolve[{y'[x] == X^2 + y[x], y[0] == k}, y[x], x], {k, 0, 4}];

Do[g[k] = 
  Plot[s1[[k, 1, 1, 2]], {x, 0, 1}, PlotStyle -> Thickness[0.007], 
   PlotRange -> All], {k, 1, 5}]

Show[g[1], g[2], g[3], g[4], g[5], v1, Frame -> True, 
 AspectRatio -> 1]
