During her time as National Secretary, Julia visited every diocese in the United States, coordinating and encouraging work in support of missions. She traveled to London as a delegate to the Pan-Anglican Congress. She traveled to Japan, China, Hong Kong and the Philippines to advance missionary work there, and to be able to report on it to the Episcopal women in the United States.
She founded the United Thank Offering (UTO). This worked by giving each woman a small box with a slit in the top and encouraging her to drop a small contribution in to it whenever she felt thankful for something. Once a year, the women of the parish presented these at a Sunday service. The money was sent to national headquarters to be used for missions.
