To find the value of the composite function $$ (f \circ h)(-4) $$, we follow these steps:

1. **Understand the Composite Function**:
   $$
   (f \circ h)(x) = f(h(x))
   $$
   This means you first apply $$ h $$ to $$ x $$ and then apply $$ f $$ to the result of $$ h(x) $$.

2. **Calculate $$ h(-4) $$**:
   Given $$ h(x) = x + 4 $$,
   $$
   h(-4) = (-4) + 4 = 0
   $$

3. **Apply $$ f $$ to the Result of $$ h(-4) $$**:
   Given $$ f(x) = x^2 + 4 $$,
   $$
   f(0) = 0^2 + 4 = 4
   $$

4. **Conclusion**:
   $$
   (f \circ h)(-4) = 4
   $$

**Answer:**  
$$ (f \circ h)(-4) = 4 $$
$$ (f \circ h)(-4) = 4 $$
