Now you have promised me complete trust in the “specialist,” and I believe that you have become fully convinced of his Party spirit and absolute devotion to the revolution. Therefore I must ask you: keep your promise to me fully (otherwise mistakes will inevitably recur). Tomorrow morning, show and explain everything to the “specialist” (while assistants are bringing up the cars and doing preparatory work). Then together with the “specialist” the experiments will be carried out without delay.

I ask you to answer me that you promise this.

Greetings! Lenin
