Подходящий конструктор копирования

Есть класс Son который наследует класс CARD, который в свою очередь наследует класс MARSH. Когда я пишу к примеру cout << (Son)So; Пишет что нет подходящего конструктора копирования, что с моим конструктором не так?

Son(Son &z) :CARD(z)
    {
        n = z.n;
        nd = z.nd;
        na = z.na;

        if (z.card != NULL)
        {
            CARD *t5 = new CARD[z.n];
            if (t5 == NULL)
            {
                exit(1);
            }
            for (int i = 0; i < n; i++)
                t5[i] = z.card[i];
            card = t5;
        }
        else
            card = NULL;
        if (z.dep != NULL)
        {
            COUNTOFTRAIN *t1 = new COUNTOFTRAIN[z.nd];
            if (t1 == NULL)
            {

            }

Класс 1:

class MARSH

    string arrivalpoint;
    TIME time;
    int trainnumber;
    MARSH() 
    {

        trainnumber = NULL;
    }
    MARSH(MARSH &z)

        arrivalpoint = z.arrivalpoint;
        time.hours = z.time.hours;
        time.minutes = z.time.minutes;
        trainnumber = z.trainnumber;
