Letter From Henry Ward Beecher.l i t Lytn m fami y to the number of eev* tu hundred htid a union at Northamp ton, Maos, one day last week. They had speeches, a poem and the following charac teristicletter from Henry Ward Beecher:Pf.ekskill, Aug 4,1869.A E Lvmas—Dear Sir : It is true that Iam a Lyman. I am also a Foote, a Chapin, a Ward, and I know not how many others. But Lyman is late blood in the family. My father’s mother was a Lyman Irom Middlo-iidd, Conn. From her he received the name Lyman Beecher. From the same blood also he received a certain hopelul, buoyant temperament which nelped him to overcome a slight hypochondriac taint which he received irom his father, i have been suspected myseii of having some ol that cheerfulness and hopefulness which is re* puled to belong to the real Lyman stock I should come to your meeting if it was in my power, and help you celebrate fbe vir* lues ol a common ancestry. But I cannot get lcavt of my engagements. The blood is prolific. It all the Lymans should come to M nut Tom, the mountain could not hold them May they still increase. I never heard ol a Lyman that was hung, or deserved to be. All that I ever knew were worth knowing. One I loved very much—Elizabeth Lvman, from Middleford, who married a Rev Mr Mills. She is now dead. But in 18341 made my first journey to Cincin* nati with her and a goodly company, among which she stood greatly beloved by all. We made a quick passage, be ng only ten days Irom New York to Cincinnati. I send my most affectionate salutations to all my cousins. I dare not trust you to offer in my behalf a kiss of salutation. But,to all who are entitled to call me cousin, I send through the air an invisible messenger, charged to perform lip service in the name of n.y paternal grandfather. I am truly yours, Henky Wahd Beecher,Bon of Lyman Beecher.
