One can usually judge the extent of damage caused by the blight by the number and vitality of the basal shoots, a large number of basal shoots indicating a heavy attack. However, if the roots have been severely injured, perhaps by short-tailed mice, as sometimes happens, no basal shoots appear, in which case the tree is doomed. If no blight is present, but one or more basal shoots appear (sometimes due to shrubby ancestors), it is advisable to inarch these as an insurance against possible trouble in the future. This inarching process has not received the attention it deserves. There is absolutely no reason why, if this method is followed, there should be _any_ death from blight in resistant hybrids or in Japanese or Chinese chestnuts, barring, of course, cases where roots are attacked by mice (or _Phytophthora_ in warmer regions). Those of our trees in Connecticut which have been blighted have continued in health and nut-bearing ever since we began the inarching method in 1937 (Fig. 4). If the inarches become blighted, they can themselves be inarched, as shown. [Illustration: Fig. 3. Veneer crown grafting on chestnut. Photo by B. W. McFarland, Conn. Agric. Expt. Sta.
