Universities there, a special course of lectures is devoted to Prof. Bose's investigations on plant irritability...."[39] The Columbia University, the largest in the United States, requested Dr. Bose to provide facilities in his Laboratory "for the reception of foreign students, who are desirous of familiarising themselves first hand with his apparatus and methods." WHAT DR. BOSE SAW IN JAPAN Dr. Bose then came back to India, in June 1915, _via_ Japan. During his stay, in Japan, he acquainted himself with the efforts of the people and their aspirations towards a great future. He found that, "in materialistic efficiency, which, in a mechanical era, is regarded as an index of civilisation, they have surpassed their German teachers. A few decades ago, they had no foreign shipping and no manufactures. But, within an incredibly short time, their magnificent lines of steamers have proved so formidable a competitor that the great American lines in the Pacific will soon be compelled to stop their sailings. Their industries again, through the wise help of the State and other adventitious aids, are capturing foreign markets. But far more admirable is their foresight to save their country from any embroilment with other nations with whom they want to live in peace. And they realise that any predominant interest of a foreign country in their trade or manufacture is sure to lead to misunderstanding and friction. Actuated by this idea, they have practically excluded all foreign manufactured articles by prohibitive tariffs."[40] "Is our country slow to realise the danger" asks Dr. Bose "that threatens her by the capture of her market and the total destruction of her industries? Does she not realise that it is helpless passivity that directly provokes aggression?... There is, therefore, no time to be lost and the utmost effort is demanded of the Government and the people for the revival of our industries...."[41] A PATRIOTIC CALL "A very serious danger" continues Dr. Bose "is thus seen to be threatening the future of India, and to avert it will require the utmost effort of the people. They have not only to meet the economic crisis but also to protect the ideals of ancient Aryan civilisation from the destructive forces that are threatening it.... There is a danger of regarding the mechanical efficiency as the sole end of life; there is also the opposite danger of a life of dreaming, bereft of struggle and activity, the degenerating into parasitic habits of dependence. Only through the noble call of patriotism can our nation realise the highest ideals in thought and in action...."[42] BACK TO INDIA After his return to India, Dr. Bose attended the Indian Science Congress at Lucknow. He then attended the ceremony of the laying of the foundation stone of the Hindu University at Benares. On that occasion he delivered a masterly address. He said:--
