obstacle presents itself—the tiny back yard does not belong to 
one boy or even to one family but must be shared by all the 
dwellers of the tenement and Johnnie’s space dwindles down to 
perhaps only room for a hill of corn; and then the high board 
fence keeps out the sun. We have been saying that even one 
bean plant or one hill of corn is worth while, but how much more 
worth while if, by concentrated efforts, all those back fences could 
be torn down and a Block Park Garden could be established. 
There could be the grass plot in the center where children could 
play, borders of flowers cared for by the children of the block, 
settees for tired mothers and babies, and a resting place for work-

“An arc light would be a great asset. Block Park Gardens 
surely would help solve the tenement problem, for they mean a 
breathing space to each block, and keeping the children off the 
streets.”

one of the board of editors of the American Journal of Botany. 
In Series IV, the fourth year of the Leaflets, fourteen num- 
bers were issued. Their popularity is attested by the fact that
