The last May number of the Horticulturist is historically a curiosity, as from it dated a series of articles in reply which exercised the writers in various ways, according to temperament; they have ever since been discussing it, and now Mr. Allen asks to sum up, not having changed his opinion by the flood of ink. Well - the atmosphere is now cleared - the lightning ceases, and we have an open field for further experiments, the discussion having prepared some for even more active exertions in behalf of pear culture, and others for renewed care of their trees. Let us all now see what will come of it, looking rather to facts than theories, and eating as many pears as we can get, while we leave a share for the expectant public. For one and all, we wish success to their brightest hopes, and in time we may see a full market supply. Mr. Allen writes forcibly, but we have been obliged to curb him a little; we can assure his readers that he is a much more amiablo gentleman than some might suppose, from the turn of some of his sentences.
