Nor are we to rest in the frustrated success of some 

 single experiments, but to proceed in attempts in the 

 most unlikely unto iterated and certain conclusions, 

 and to pursue the way of ablactation or inarching. 

 Whereby we might determine whether, according to 

 the ancients, no fir, pine, or picea, would admit of any 

 incision upon them ; whether yew will hold society 

 with none ; whether walnut, mulberry, and cornel 

 cannot be propagated by insition, or the fig and quince 

 admit almost of any, with many others of doubtful 

 truths in the propagations. 



And while we seek for varieties in stocks and scions, 

 we are not to admit the ready practice of the scion 

 upon its own tree. Whereby, having a sufficient 

 number of good plants, we may improve their fruits 

 without translative conjunction, that is, by insition of 

 the scion upon his own mother, whereby an handsome 

 variety or melioration seldom faileth we might be 

 still advanced by iterated insitions in proper boughs 

 and positions. Insition is also made not only with 

 scions and buds, but seeds, by inserting them in cabbage
