Sir: I hereby present the annual report for the Department of 
Elementary Instruction. 
Some of our high spots are the following. The attendance at 
our regular Garden classes has been over 55,000, and the attend- 
ance at visiting classes, 60,000. Taking all the phases of our 
work, we have contacted over 1,000,000 children. ‘The last figure 
represents our classwork (visiting and regular), conferences, seed 
distribution, and supply of material to schools. We have reached 
over 95 per cent of our Brooklyn elementary schools, even though 
the visiting classwork was affected during the fall by the epidemic 
of infantile paralysis, when schools were asked for some weeks not 
to send any classes out from their schools.
